Triangular Energy Saving Route Protocol by Energy Sieving in Wireless Ad Hoc Networks

In grid-based routing protocol, one node in a grid is elected as the grid leader. However, nodes consume extra energy for in the traditional grid leader election, especially in a high node density environment. In this paper, we propose a triangular energy saving route protocol by energy sieving (TESRES) to address this issue. In TESRES, a new grid leader election and a triangular route discovery are proposed. In the grid leader election of TESRES, only few nodes are elected as a grid leader in the grid leader election. In the route discovery, TESRES selects the energy-efficient routing path to reduce energy consumption for transmitting packets. Therefore, TESRES could save energy for data transmission and prolong the lifetime of route. In the simulation results, TESRES could reduce 16% and 28% of energy consumption in the grid leader election and route discovery, respectively.
