New power-aware routing protocol for mobile ad hoc networks

Since devices used in wireless mobile ad hoc networks are generally supplied with limited autonomous resources, energy conservation is one of the most significant aspects in these networks. Recent studies show that the energy consumed for routing data-packets in mobile ad hoc networks can be significantly reduced compared with the min-hop full-power routing protocols. One of the promising mechanisms proposed in literature to reduce the energy consumption is the transmission power control. In this paper, we define new routing metrics to strike a balance between the required power minimisation and batteries freshness consideration. We also define a new technique which allows the distribution of the routing task over nodes. Using these metrics and techniques we derive from DSR [2] a new power-aware and power-efficient routing protocol, whose performance is analysed by simulation in different situations of mobility and network load

Energy Consumption Models for Ad-Hoc Mobile Terminals

This paper describes a set of experiments based on ACPI BIOS measurements which evaluate the energy consumption of an IEEE802.11 wireless network interface. Based on our ACPI measurements, two models of energy consumption are presented in section 6: (1) an analytical model for network simulator, (2) an empirical model for testbed implementation. The aim of these studies is to provide an environnement both for simulation and implementation. This work is the rst step to propose a new power-aware routing protocol for mobile ad-hoc networks
