Router performance with AoI and RoI routing for wireless sensor networks

In order to achieve the best performance of a Wireless Sensor Network (WSN), it is a must to provide a challengeable routing algorithm, which consumes less power and allows more data collection. In this paper we have considered a WSN with mobile sinks and it is considered that the router follows the basic location update algorithm with traffic awareness. We show the performances of a router under two different scenarios. In the first scenario, all the mobile sinks are allowed to move around the entire area of interest (AoI). In the second scenario, regions of interest (RoI) are defined for all mobile sinks. The performances of router under different scenarios are simulated using matlab simulation. Based on the applications of the wireless sensor network and its requirements, the scenarios can be selected. But the results shows that for the energy constraint cases it is better to select the RoI scenario by which lifetime of the network can be saved for a long time with reduced energy spent.
