Topology control in MANET for efficient energy conservation

The MANET is a Mobile Ad - hoc Network. Topology control is an important issue in design of MANETs, due to its nature of the node - mobility. Many solutions are available for topology control in ad - hoc networks, centralized or distributed algorithms like - i.e. GAF, LEACH, AFECA etc.The basic idea for topology maintenance is to elect the leader and all the moving node information is collected by it. This basically referred as clustering in ad - hoc communication. This paper proposes an energy conservation scheme f or multi - hop ad - hoc wireless network, where it reduces energy consumption during idle - listening, without significantly diminishing the capacity or connectivity of the network. It is built on the observation that, when a region of a sufficient density of no des, only a small number of them need to be ready at any time to forward traffic for active connections. It uses the clustering mechanism in a distributed manner. The main issue in design of such scheme is to choose the node status be - active or power save , in order to provide energy efficient communication. In this paper, we propose a schematic for the improved forwarding backbone mechanism, which reactively utilizes information about ongoing communication as well as the current power management mode of no des along potential routes. This proposed design reduces the energy consumption for the overall network by almost 30%, and also with satiable network performance. By the results and their analysis, it can be concluded, that this algorithm preserves capacit y and connectivity of network, decreases latency, and also provides significant energy conservation
