Energy Efficient Power Aware Multipath Dynamic Source Routing

Abstract

Mobile Ad-hoc Networks (MANET) are consisting of nodes that have limited battery power so the energy efficiency is one of the primary metrics of interest. Energy efficient routing is a major issue in MANET. This paper proposed an Energy efficient power aware multipath dynamic source routing protocol by modifying one of the most popular routing protocols that is Dynamic Source Routing (DSR) protocol which is not at all concerned about power consumption. The proposed Dynamic source routing-Power Aware routing DSR-PSR uses the basic concept of traditional DSR and implements energy efficient routing through which it not only enhances the life time of the network but also increases the overall performance of the networks. General TermsEnergy Efficient algorithm for Dynamic source routing protocol.

Using a New Routing Metric in Paths Discovery Process for MDSR

“…Therefore, many researches in recent years proposed various power aware metrics in traditional routing protocols that depends on finding the shortest path with minimum hop count without taking into account the selected rout power, for decreasing power consumption and selecting paths that have maximum residual energy.This paper proposes a new metric to select the route path in MDSR routing protocol based on the ratio between the residual energy of the node and the hope counts then the proposed routing protocol is compared with the original MDSR and other existing routing protocols as well to assess its efficiency.Many researchers have been done to update dynamic source routing (DSR) protocol in such a way to reduce the power consumption in one hand, and increase the network lifetime on the other hand. Some researches modified the way of route selection in DSR route discovery phase by taking the transmission power of the node and residual energy into account during the process of selecting routes between source and destination as proposed by Aye and Aung [1].Sharma [2] proposed a new routing protocol called Dynamic Source routing-power-aware routing DSR-PSR. The source node checks if a particular destination in the route cache exists, if the destination is found, then use that path to send a data packet, else route discovery process is used, in this process route request (PREQ) packet broadcasted by the source, each node adds to request node ID and battery status B-S.…”

“…A. Route discovery process  Route discovery process begins when node "S" wants to send data to the destination node "D" but doesn't know any information about routes lead to that distention, therefore "S" sends RREQ packets to all of its neighbors (2,6,8) asking for route to "D".  Node D received the RREQ packet and sends back the reply packet RREP to the source node S over node 4, node 7 and node 9.…”

A Survey on Energy Efficient Routing In MANETs Using MultiObjective Genetic Algorithm

“…The network does not have any central administration device such as access points or base stations. Since the nodes are mobile in nature, ad hoc network do not have any pre-defined structure [1]. In ad hoc network, all nodes are supported by battery powers with limited capacity.…”

“…Ad hoc network do not have any former infrastructure i.e. they are infrastructure less in nature [1]. They interact with each other directly or indirectly with intermediate nodes [3].…”
