Lifetime maximization in wireless sensor networks using dstar-lite algorithm

Abstract EN

Wireless sensor networks (WSNs) are energized by inexpensive batteries with limited power.

A remarkable amount of energy is consumed by wireless data transmission.

Therefore, energy efficient routing protocols can conserve battery power and gives the network longer lifetime.

Using complex protocols to plan data routing can efficiently reduce energy consumption but it can produce delay processing.

This paper proposes a new routing method that incorporates dstar-lite to find the optimal path from the source to the destination.

The proposed method reuses the path until a specific amount of energy consumed in such a way that keeps energy consumption fairly distributed over the nodes of a WSN while reducing the delay of calculating the routing path from scratch.

Simulation results demonstrate the effectiveness of the proposed method in terms of reducing energy consumption and decreasing end-to-end delay as compared with fuzzy logic and a-star algorithm.

The results also show that the network lifetime achieved by dstar-lite could be increased by nearly 20% and 24% more than that obtained by fuzzy logic and a-star algorithm, respectively.
