A mobile ad-hoc network (MANET) is usually power constrained due to the limited battery energy on each node. For MANETS, energy efficiency is crucial for the design of new routing protocols. In this paper, a new energy-aware routing algorithm, called Energy Saving Ad-hoc On-demand Distance Vector (ESAODV) routing, is proposed. In the route discovery process of ESAODV, intermediate nodes estimate the...
Battery energy limitation is one of the main challenges in the mobile ad hoc networks. Several hardware and software based techniques have been proposed in this field. Energy aware task scheduling is one of the software methods where the scheduling policy aims at optimizing the energy. Most of the previous work have achieved significant energy savings for individual mobile nodes but did not consider...
The problem of TCP and all its existing variations within MANETs resides in its inability to distinguish between different data packet loss causes. Thus, TCP has not always the optimum behaviour in front of packet losses which might cause network performance degradation and resources waste. Multiple loss differentiation algorithms (LDAs) have been designed to improve TCP performances. They had been...
In this paper, we attempt to elongate the network lifetime by balancing energy usage, namely, allocating packets via multiple paths proportionally to the energy metric of each path. We propose the static and dynamic strategies of collecting energy metric values and allocating packets, and apply them to AOMDV. Performance comparisons of the proposed methods and original AOMDV are carried out in simulation...
This paper introduces a message forwarding algorithm for search applications within mobile ad hoc networks that is based on the concept of selecting the nearest node from a set of designated nodes. The algorithm, which is called Minimum Distance Packet Forwarding (MDPF), uses routing information to select the node with the minimum distance. The goal of the proposed algorithm is to minimize the average...
Mobile ad hoc networks are a class of dynamic networks without any centralized administration. A major bottleneck in mobile ad hoc networks (MANETs) is the energy consumption since nodes are usually mobile and battery operated. To maximize the lifetime of mobile ad hoc networks (i.e., the lifetime of the nodes themselves) the power depletion of network must be evenly distributed, i.e., there must...
A fundamental problem of mobile ad hoc network (MANET) is to determine whether it is advantageous to route packet over many short-hops or few long-hops. The main arguments for short-hop routing are minimum energy consumption and high signal-to-interference ratio. Minimum energy consumption maximizes network life. High signal-to-interference ratio maximizes network capacity. On the other hand, main...

Recently power-aware routing algorithms for wireless ad hoc networks have drawn more and more attention. In this paper, we are focused on the routing algorithms aimed at maximizing networks lifetime. We provide a new maximum-lifetime routing algorithm DNLBR, whose routing procedure is directly based on the node lifetime, and we give a formal proof for its correctness. Moreover, by integrating power...
As the growth of multimedia communications involving digital audio and video, it is increasingly important for the MANET (mobile ad hoc network) routing protocols to simultaneously support both real-time and non-real-time traffic. MANET energy management should offer this support because devices are equipped with limited battery power. To achieve this end, we revise the ad hoc on-demand distance vector...
Dynamic Source Routing (DSR) Protocol is a commonly applied reactive protocol for mobile ad hoc networks (MANETs). When the network size is increased, overhead is increased due to the source routing nature of DSR. Moreover, energy consumption of the nodes increases, as the nodes act as intermediate nodes for many source destination pairs. In order to improve the scalability of DSR, in this paper,...
Obviously, the energy is one of the important metrics to consider when designing communication protocols for mobile ad hoc networks (MANETs). In this paper, we demonstrate the importance of considering energy saving in MANETs. Our analysis are based on the comparison of two energy-based mechanisms called E-AODV, an energy consumption rate-based routing protocol, and F-AODV, a cross-layer-based routing...
