Performance of Wireless Sensor Network under various energy models, routing protocols and node mobility conditions

Wireless Sensor Network often operate under strict energy constraints. So, reducing energy consumption at each sensor node without affecting the overall throughput becomes a desired goal for all researchers and designers. There can be various energy conservation schemes in a typical WSN e.g. energy efficient routing, node scheduling, clustering, mobility models etc. In this paper three scenarios based on mobility conditions have been proposed. These three scenarios have been evaluated under the three existing energy models namely GENERIC, MICA MOTE and MICAZ and two routing protocols Ad Hoc On demand Distance Vector (AODV) and Dynamic MANET On demand (DYMO). It has been found that the MICA MOTE energy model consumes the least energy as compared to the other two energy models. The evaluation of the three mobility scenarios under the two routing protocol indicates that DYMO is well suited for the mobile networks.
