In this work, we are interested in characterizing the performance of decentralized multiple-access and retransmission schemes for wireless ad hoc networks. We are considering a regular linear network model of sender/receiver pairs, where nodes transmit their information messages over a common radio channel. We obtain expressions for node throughput as a function of inter-node separation for dif...

Mobile Ad hoc Networks (MANETs) are typically considered to be stand-alone autonomous networks that support multi-hop communication without relying on an existing infrastructure. The integration of MANETs and the internet extends network coverage and facilitates hybrid wired and wireless networking. Most earlier approaches, for integrating MANETs with the internet considered fixed gateways and ...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...

Mobile ad hoc networks (MANETs) are formed by mobile nodes without the support of fixed infrastructure. In the MANET, each node performs as a host as well as host to forward the data packets. The nodes are adjustable based on the local environments. MANETs are used in many situations where temporary network connection is needed. In this paper, investigates the problem of lifetime enhancement of...

IP anycast allows a source node to transmit IP packets to a single destination node, out of a group of destination nodes. It can be an important paradigm for an ad-hoc network in terms of resource, robustness and efficiency for replicated service applications. DSR is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. This...

Mobile Ad-hoc Network (MANET) is an autonomous, multi-hop and dynamic network composed of number of wireless mobile nodes. Routing protocols are challenges in designing Mobile Ad-hoc networks with low energy consuming and low control overhead. Ad-hoc on demand distance vector routing protocol (AODV) is specially designed for mobile ad-hoc networks with Expanding Ring Search (ERS) technique for ...

The number of hops between the source and destination nodes is a key parameter in studying multi-hop ad hoc networks analytically. To the best of our known, there is no analytical work that considers the hop count of paths in MANETs in a random mobility environment. This paper presents a theoretical study for the expected number of hops between any random source-destination pair in multi-hop ad...
