An Intelligent Gateway Scheme for Power Aware Routing in Mobile Ad Hoc Network

A Mobile Ad hoc Network commonly called as MANET provides the technical platform for efficient information sharing in emergency and rescue operations without any centralized access point and infrastructure. The nodes move arbitrarily and its topology also changes frequently and unpredictability. For ad-hoc networks every node communicates with other nodes in multi-hop manner through intermediate nodes directly or indirectly. Mostly mobile ad hoc network nodes are battery operated and in most cases they are installed in an environment where it may be impossible to retrieve the nodes in order to charge the batteries. Therefore, network nodes need to be energy conserving so that the battery life and hence the network lifetime can be maximized and it is important to minimize the power consumption of the entire network to have optimized power battery life. In this paper we propose an (IGPARS) intelligent gateway scheme for power saving features and a solution to reduce the number of collision so that minimum power will be required in routing. The selection process for determining the best gateway intermediate node carried out in order to efficiently route the data packets after a regular interval of time. This process helps in reducing the overall delay involve in transmission of message from source to destination node and the bandwidth is appropriately utilized.
