On the Lifetime Maximization Design of Mobile Ad Hoc and Sensor Networks

One critical issue in the design of mobile ad hoc and sensor networks is to select some parameters that can guarantee a longer time period during which these networks are fully working. To maximize this period, which is called the network life-time: a new method is proposed. For this purpose, a radio link availability estimate as well as a routing parameters, such as the movement directions, speed, actual interference, path availability, etc., are used. With this method an optimal assignment of mobile nodes to clusterheads at each time step was obtained. The given approach allows to maximize only the minimum lifetime without creating topology or also to create the topology after having done the previous work. We validated our approach through simulation and showed that the proposed framework is well suited for the designing of mobile ad hoc and sensor networks.
