Genetic algorithm for effective optimization of delay performance in wireless sensor networks

الملخص EN

Wireless sensor networks (WSNs) play an important role in many real-world applications like surveillance.

Wireless networks are also used to have data transfer.

In such cases, there are problems with resourcece- constraintnednetworks.

The problems include a delay in communication and reduction in Quality of Service (QoS).

Topology control can solve this problem to some extent.

However, the delay performance and QoS need to be improved further to support intended operations in wireless networks.

When relay node concept is considered, it is possible to optimize performance in such networks.

In this paper, we proposed a Genetic Algorithm (GA) based relay configuration for optimizing delay performance in WSN.

Relay nodes compute optimal positions using the proposed algorithm so as to improve QoS and reduce delay as much as possible.

We implemented the algorithm using NS2 simulations.

The results revealed that the proposed approach is able to improve QoS, reduce delay besides improving network performance in terms of throughput, network capacity, and energy efficiency.
