Design and analysis of energy aware interior gateway routing algorithm with particle swarm optimization

In wireless sensor networks (WSNs), the data must reach a processing node with less energy consumption and delay rate. However, with the specific consideration of the unique properties of sensor networks such as limited power, stringent bandwidth, dynamic topology due to node failures, adding/removing nodes, or even physical mobility, high network density and large-scale deployments have posed many challenges in the design and management of sensor networks. These challenges have demanded energy awareness and robust protocol design. Efficient utilization of the sensor's energy resources and maximizing the network lifetime were the primary design considerations for the proposed work. As a result, the new interior gateway routing with particle swarm optimization (IGRPSO) is presented with minimal latency and a higher packet delivery ratio in WSN; optimum link weights are calculated in a fraction of the original data to the new protocol. Network entropy maximization is a conceptual framework that guides the development of the protocol and the computational techniques required to determine which traffic distributions are not only best but also realizable through link-state routing. Therefore, a routing algorithm provides the optimal and economically optimal route. We used the MATLAB simulation environment to compare and contrast the performance of the dynamic source routing (DSR) protocol and enhanced interior gateway routing protocol, DSR protocol with particle swarm optimization with that of the IGRPSO protocol, which has the maximum packet delivery ratio of 75.74% and less packet drop of 25.37%, less energy consumption of 0.3674 J.

Automated summary

In wireless sensor networks, the challenge lies in designing and managing the networks considering limited power, stringent bandwidth, dynamic topology, and high network density. The proposed IGRPSO protocol addresses these challenges by optimizing routing with minimal latency and a higher packet delivery ratio.
