Abstract

An important and essential issue for mobile ad hoc networks is routing protocol design that is a major technical challenge due to the dynamism of the network. The primary goal of such an Ad hoc Network routing protocol is correct and efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. Although establishing efficient routes is an important goal, a more challenging goal is to provide energy efficient routing protocols, since a critical limiting factor for a mobile node is its operation time, restricted by battery capacity. To improve network lifetime energy balance is an important concern in such networks. The principal focus of this survey is on how to maximize the useful lifetime of ad hoc wireless networks through energy-efficient routing. It is aimed to reveal the factors that influence the depletion of energy in ad hoc networks. This should aid the design of energy-efficient solutions. This paper provides a study on routing protocols and balanced energy consumption protocol.

Abstract

Energy conservation is of great importance for mobile ad hoc networks in which most nodes are equipped with limited energy sources. This paper presents a survey on energy efficient routing protocols for wireless Ad-Hoc networks. Survey focus on recent development and modifications in this widely used field. This discussion is centered on proposed power saving algorithms. By utilizing the inherent device heterogeneity, a cross-layer designed Device-Energy-Load Aware Relaying framework, named DELAR, to achieve energy conservation from multiple facets, including power-aware routing, transmission scheduling and power control is studied. Besides it this paper discuss about the conventional protocols and also see how these are modified to make these protocols energy efficient and what the shortcomings that have been resolved. Many unsettled problems need to be defined and solved in this area. It is firmly believed that this domain will greatly advance in the future. This evaluation may prove to be an essential step for the development and improvement of new techniques in this area.

Abstract

Energy efficient routing in ad hoc networks has been the subject of intensive study in recent years. Most work has been focused on residual battery power related cost metrics for a homogeneous ad hoc network, where all the nodes are considered identical in terms of functioning and available resources. Energy conservation is of great importance for mobile ad hoc networks in which most nodes are equipped with limited energy sources. This paper addresses energy conservation, a fundamental issue of paramount importance in heterogeneous wireless ad hoc networks consisting of powerful nodes (i.e., P-nodes) as well as normal nodes (i.e., B-nodes). By utilizing the inherent device heterogeneity, a cross-layer designed Device-Energy-Load Aware Relaying framework, named DELAR, is proposed to achieve energy conservation from multiple facets, including power-aware routing, transmission scheduling and power control. We propose an Asymmetric MAC (A-MAC) as an elegant solution. Taking full advantage of P-nodes, DELAR can significantly prolong the network lifetime. It strikes a good balance between power efficiency and the overall system performance.
