An adhoc network is collection of wireless mobile hosts, which form a temporary network by using reconfigurable structure that means it doesn't use fixed infrastructure to form a temporary network. It will connect all nodes through wireless technique. Hence it can change the link between one node to another node during run time, when the link failure problem occurs. There is a limited range for each...
The standard routing protocols are used to find an optimal path between two given endpoints. Nowadays, the solution of multipath routing becomes fundamental requirement to improve the overall throughput of networks. On the other hand, due to the dynamic and high volume of traffic, it is also more challenging to control the congestion in an efficient way within the networks. Recently, Software-Defined...
In the existing system, the node may sometimes behave selfishly. To act selfishly means that nod sometimes is unwilling to forward the packets to the further node as prescribed in route from source to destination in order to save their resources and this may seriously affect the performance of the network. In the proposed system, the network is distributed into clusters and every cluster has their...
Mobile Ad-hoc Network is one of the popular technologies among the various wireless technologies. The MANET is an ad-hoc technology and inherits the properties of mobility, wireless connectivity and independence. In one side it demonstrates the advantage over applications on the other side that is complicated to manage. Therefore the routing protocols are an essential component of the entire network...
A Wireless Sensor Network is an assortment of nodes organized into a cooperative network. Wireless Sensor Networks (WSNs) are subjected to node failures because of energy constraints; also nodes can be added to or removed from the network upon application demands, leading to unpredictable topology changes. Bursty traffic resulted from the detected events will simply cause congestion within the networks,...
In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
Previous studies have shown that opportunistic routing (OR) can significantly improve the performance of wireless multi-hop networks, such as wireless adhoc networks and wireless sensor networks. However, most existing opportunistic routing schemes only consider node location as the priority metric in relay selection, where packets may accumulate in relays' packet buffer, especially in data intensive...
Aggregating common-path network flows (in the network interior) helps in improving the applications delivery performance. From the network edge perspective, the sender and receiver-ends of the respective applications need to have a typical one-to-one mapping. An aggregation framework in the network therefore needs an effective forking to maintain the one-to-one mapping of the flows. In this demo,...
MANET is a self-sorting out, decentralized, framework less, multi hop, remote system of cell phones. routing protocols assume a crucial part in transmission of information over the network. Streaming video is content sent in packed frame over the Internet and showed by the viewer continuously. Mobile Ad hoc Networks are considered for some applications. Routing protocols are the most imperative component...
It is critical to provide sustained data throughput in edge computing, where several sensor devices generate information that needs to be fused and used for decision making in e.g., disaster incident scenes. To this end, we compare the effectiveness of two protocols, Hybrid Wireless Mesh Protocol (HWMP) and Greedy Perimeter Stateless Routing (GPSR), based upon their ability to stream data in a mesh...
This paper analyzes the significant low performance of Backpressure routing protocols when combined with TCP-based flows. The issue is due to a mismatch between i) the congestion control mechanism of TCP and ii) the multi-path nature based on queue backlogs differentiation of the Backpressure algorithms. We aim to address this issue by introducing and evaluating two novel schemes within the Lyapunov...
The rapid development in communication approach has brought out new mode of communication. Among the recent developments, adhoc network has emerged as new mode of data communication. The objective of link reliability is a major concern in such network. In this paper, a new approach to route discovery based on network power and operational characteristic is proposed. The approach suggested, results...
VANET is the network which monitoring the traffic on the road and share the information with neighbors. Movable nodes (vehicle) and fixed node (RSU) are used in VANET. This network is about the safety purpose of driver and sharing confidential information about traffic and accident. On network some vehicles do not share information, send fake requests and try to break network security. Lots of techniques...
Cluster computing in ad hoc network draws special attention from the research community due to its inherent support for group communication in varied application domains like emergency and rescue operations, etc. Context sensitive aware cluster computing yields maximum benefits and advantages than the traditional computing. The Cluster Head (CH) and the Cluster Members (CM) effectively coordinate...
The aim of this manuscript is to propose a secure handoff scheme for cognitive radio network by ensuring a secure communication among cognitive users (CU). A coordinator cognitive user(CCU) is selected based on users trust values/factor (TV/TF) by periodically computing and updating these values of each CU depending upon their characteristics. The CCU is the controlling unit to allow the unused band/channel...
Delay Tolerant Networks (DTNs) are characterized by node mobility and partitioned network topology, extremely long delivery latency, etc. Consequently, the traditional ad-hoc routing algorithms cannot work well in DTNs. In order to provide effective communication services in DTNs, in this paper, we propose an adaptive routing based on Node Performance and Encountering Probability (NPEP). NPEP chronologically...
There has been rapid growth in the area of wireless communication by Wireless Mesh Networks (WMNs) where routing metric is the key metric to find the optimized route in WMNs. For obtaining optimal performance, integrating multiple performance metrics into a routing protocol is effective, as single metric will not be able to satisfy the thorough requirement of WMNs. This paper has proposed a new routing...
MANETs is collection of wireless network establishing a network in which nodes communicate with each other by network systems such as the Internet. MANETs routing protocols are characterized into two types, for example, table-driven and on-request or demand. In this network node performed as a function of routers which discovers and maintain the path to other node. In Adhoc network nodes are easily...
Due to their intrinsic characteristics, Ad Hoc mobile networks could be subjects to disturbances or node break-downs. The latter are worsened by the nodes relay and mobility features. A more sophisticated Multihoming integration to MANET networks necessarily increases its robustness: in other words, it improves its performances. That is why we suggest in this article a new extension of the Stream...
The proposed work aims at designing routing method and data compression algorithm for WSN's. An ad-hoc network (WANET) is considered and based on certain criteria the data is forwarded dynamically. Various parameters such as Compression Ratio, Packet Delivery Rate, Energy consumption are considered to determine the efficiency of the network. One of the primary parameters to be considered in the configuration...
