The growing of the internet use is proportional with the growing of IP address needs, but the increasing of the IP use is not equal with the number of available IPv4. Then, IPv6 was developed as a solution to overcome the limited amount of IPv4 address. Readiness of various aspects ranging from infrastructure to a service provider is required to implement IPv6. In order to improve the quality of IPv6...
Analysis of Network Intermediate Connectivity is one of the important and challenging issues in Vehicular Adhoc Network (VANET). Gradually, intermediate connectivity among the nodes becomes a popular interesting research paradigm in high mobility domain. It depends upon the movement pattern of the vehicles and the routing of packet transmission depends upon the connectivity of the nodes. Among the...
For minimizing road accidents, traffic jams, car parking and other significant scenarios related to cost effectiveness and safety in VANET, the communication between vehicle to vehicle and vehicle to road side unit (RSU) should achieve the service quality, high data receive ratio and low latency. However, the probability of TCP disruption increases by the increasing distance between source and destination...
A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility. This paper presents a detailed study and analysis of various routing issues...
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...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
With the features provided by wireless mesh networks (WMN) and the increasing number of users, the Quality of Service (QoS) has become essential to support multimedia applications. In addition, employing the multichannel approach has led to the improvement of the network performance. However, selecting a path with the maximum available bandwidth to transmit data from the source to the destination...
Wireless mesh network (WMN) is a peculiar type of growing technology that can alter the world more effectively in the coming decades. Multicast routing in mesh networks is the distribution of data from a single source to multiple destinations or multiple sources to multiple destinations through the intermediate nodes. There can be many numbers of intermediate nodes between source and destination....
The Quality of Service (QoS) on the traffic environment with high mobility, dynamic topology, and change trajectory is one of the challenges in the use of Vehicular Ad-Hoc Networks (VANET) Routing Protocols. PUMA routing protocol presents multicast work mechanism based on shared mesh topology. It always dynamically adapt to VANET traffic conditions. In this paper, we evaluated the PUMA routing protocol...
Delay and capacity (throughput) are two important parameters to route data packets in Mobile Ad Hoc Networks (MANETs). In this paper, a new connectionless routing algorithm has been proposed to overcome the performance limit. The proposed algorithm is an extension of dynamic virtual route (DVR) algorithm. Mobility degree of nodes' neighborhood is used to calculate two mobility metrics. Mobility metrics...
Data centers are used to host computation-intensive distributed applications. Since all the applications are distributed in nature, their performance is significantly affected by the communication network. These applications generally create two kinds of flows: large data flows that require high throughput and small control flows that require low delay. These two contradictory requirements are not...
A mobile ad hoc network is much more assailable to attacks than a wired network due to its limited physical security, high mobility and lack of centralized administration. Jellyfish is a new denial of service attack. There are three kinds of JellyFish attacks i.e. JF Reorder Attack, JF Periodic Dropping Attack, JF Delay Variance Attack. In JF delay variance attack, intruder node needs to intrude into...
Ad hoc On-demand Distance Vector (AODV) is one of reactive routing protocol in Mobile Ad hoc Network (MANET) and many variants are developed based on modifying this protocol. Purposes of modification were mostly related to security and performance improvement, yet the additional processes being introduced in the modification could incur overheads to the modified AODV. The purpose of this paper is...
