In this paper we consider the selection and deployment of MANET protocol to efficiently route the traffic and communicate in Tactical Battle Area (TBA). Tactical Wireless Communication Network (TWCN) provides connectivity between Wide Area System (WAS) of TWCN nodes, forming a backbone transmission network. TWCN is for TBA that consists of Network Centric Systems. These entities impose routing challenges...
Propagation structure has a vital role in designing the Mobile ad-hoc networks (MANETs). Propagation structure is employed for computing signal strength about each data packet at the destination. Propagation Structures in MANETs are characterized into three categories such as Free Space structure, Two-Ray Ground structure and Shadowing structure. Here in this paper, the effect of Two-Ray Ground propagation...
MANETs are self-configuring, self-healing, and self-optimized network of devices which are mobile in nature connected by a wireless medium. All mobile nodes in “MANET” are mobile and therefore the nodes change their links with other devices very frequently. Some receiving nodes in the network maybe moved out-of-range of the sender node, therefore the data packets hops through intermediate nodes. The...
Due to high mobility of nodes, the major challenge of mobile ad hoc networks (MANETs) is the frequent link breakages which lead to numerous path failures and route discoveries. This paper introduces a novel signal strength based algorithm for RREQs forwarding (SAODV) to better exploit the neighbor coverage knowledge and hence reduce routing overhead in MANETs. The simulation results confirm the efficiency...
Adhoc networking field has been interestingly accepted by the research society due to its surprising features. Almost every aspect of the network has been explored by the researchers at some level of detail. A lot of analyses/ surveys have been presented in the literature for showing the performance of well accepted adhoc routing protocols viz. AODV, DSR, AOMDV, CBRP etc. This paper presents some...
This paper focuses on the comparative analysis of routing protocols such as Ad-hoc On-demand Distance Vector Routing System (AODV), Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR). The analysis is been made against different network parameters like network load, end to end delay and throughput in a small scale Wireless Local Area (WLAN) based Wireless Sensor Network (WSN) scenarios...
A Mobile ad hoc network consists of wireless mobile nodes those who have ability to communicate mutually while there is no role of infrastructure network or any centralized control. In order to forward packets from one node to another, a mobile node works as host as well as router. Routing protocols play a relevant role in functioning of mobile ad-hoc networks. Many routing protocols have been proposed...
An Ad Hoc network is a set of portable nodes, that could establish communication anytime and anywhere between themselves; however, a set of routing protocols is needed to set the routes between nodes in order to deliver a message from the source to the destination node. Many routing protocols have been proposed in order to achieve optimum routing performance in a mobile Ad Hoc network scenario, but...
Research and propose a path collection mechanism optimization scheme of AODV protocol. This scheme adopts the path collection mechanism in DSR protocol to improve the performance of AODV, meanwhile it avoids being affected by the high running overhead and weak scalability of DSR protocol. Results obtained by OPNET Simulation shows that the optimized AODV scheme performs effectively in terms of packet...
Mobile Ad Hoc network (MANET) is a typical self-organizing network, in which the routing mechanism should adapt rapidly to the frequently changing network topology, which remains hot for research. The article described the features of Destination-Sequence Distance Vector (DSDV), Dynamic Source Routing (DSR), Ad Hoc On-Demand Distance Vector (AODV) and Ad Hoc On-Demand Multi-path Distance Vector (AOMDV),...
Internet of things (IoT) has become an emerging new technology. Things having identities and virtual personalities use intelligent interfaces to connect and communicate within social environmental and user contexts. This paper first studied the mechanisms of some existing routing protocols such as AODV, DSR and OLSR, which is widely used in Ad Hoc networks. And then their performance in IoT circumstances...
A MANET is a infrastructure-less and auto configurable network of mobile nodes which are connected without wires. As per proposal of this paper, the communication in a MANET works on set of random keys called KEY1=X+KEY0, KEY2=X+KEY1, KEY3=X+KEY2…KEYN=X+KEYN−1 to establish the connection between nodes and applies to validate the packets. Since there could be a issue of keys length, hence we can enforce...
An autonomous collection of the mobile nodes communicating with each other with the help of wireless links either in a direct or indirect manner or rely on other mobile nodes is referred as MANET. The routing protocols in MANET are designed on the basis of the assumption that all the participating nodes co-operate with each other. Due to certain issues like open structure and limited energy supply,...
Mobile Ad Hoc Networks (MANETs) are increasingly being used in various applications for civilian, commercial, and military uses. However, unique characteristics of MANETs introduce several challenges such as routing and mobility management. Nodes frequent movements make routing more difficult due to frequent topology changes. Dynamic Source Routing (DSR) routing protocol is among the common routing...
In wireless sensor network (WSN), data collecting from the environment and sending that data to be processed and evaluated is the most important issues. Hence performance evaluation and comparison between routing protocols is required because performance of any routing protocol can be changed or very with various parameters such as speed, seed time, pause time, number of node, and traffic scenario...

In Wireless Sensor Networks (WSNs), fair utilisation of the network resources is a challenging task. In this regard, one of the determining factors is the routing protocol that plays an important role to route the data traffic from the source to the destination, under limited network resources. Most of the routing protocols and their variants in WSNs replace the routing metric of the prevalent routing...
