SSA-Based WSN Clustering Routing Algorithm for Power Grid

Due to the large number of sensors in some power grids and the lack of networking capability, a solution of arranging relay nodes to collect sensor information and networking relay nodes is proposed. For the networking of relay nodes, a clustering routing algorithm (LEACH-WGR-SSA) is proposed, which rotates the gateway of relay node network or the root node – Wireless gateway. Furthermore, Sparrow search algorithm is introduced to optimize the election of adjacent nodes and location information are considered for the election of Wireless gateway and cluster heads. Simulation results show that the LEACH-WGR-SSA algorithm prolongs the life cycle of the network, balances the energy consumption and effectively improves the convergence speed.
