Developing Quality of Service (QoS) aware routing protocol is an ever demanding task for Mobile Ad hoc Networks (MANETs). This research aims in developing Reliable Geographic Routing Protocol (RGRP) towards improving Quality of Service (QoS) in heterogeneous MANET. RGRP is an adaptive on-demand geographic routing protocol which builds efficient paths based on the need of user applications and a...

<span>Constructing a stabilized route in dynamic topology and decentralized architecture is still an unsolved problem mobile Ad-hoc networks. There are various research contributions where received signal strength has been used to enhance the routing performance. We reviewed existing technique found that adopting current strength-based mechanism not efficient enough deal with overhead ene...

In wireless ad hoc networks, the traditional routing protocols make the route selection based on minimum distance between the nodes and the minimum number of hop counts. Most of the routing decisions do not consider the condition of the network such as link quality and residual energy of the nodes. Also, when a link failure occurs, a route discovery mechanism is initiated which incurs high rout...

This work describes a novel location-aware, self-organizing, fault-tolerant peer-to-peer (P2P) overlay network, referred to as Laptop. Network locality-aware considerations are a very important metric for designing a P2P overlay network. Several network proximity schemes have been proposed to enhance the routing efficiency of existing DHT-based overlay networks. However, these schemes have some...

Routing decision plays a vital role in delivering a message to its destination in a network, especially in an opportunistic network where connectivity between nodes is unpredictable i.e. intermittent connectivity; routing decision dominates in measuring the network performance parameters. Delay Tolerant Networking (DTN) was proposed to address the technical communication problems in heterogeneo...

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile computers forming a temporary network without any fixed infrastructure. Searching for feasible paths, or routing, is very challenging in mobile ad hoc networks because of frequent topology changes caused by users’ mobility, All nodes are equal and there is no centralized control or overview. Many different routing protocols base...
