Teaching and Learning Optimization method for multi- channel wireless mesh networks with MIMO links

Abstract

Wireless Mesh Networks are a very attractive new field of research. Mesh networks are low cost, easily deployed, and provide high performance solution to broadband network access. Multiple Inputs and Multiple Outputs (MIMO) is one of the radio technology breakthroughs for increasing network capacity to obtain the full benefits in wireless mesh networks. The proposed research investigates the network routing, channel assignment, capacity of MIMO channel with number of transmit and number of receive antennas in wireless mesh networks. This paper also focuses an intelligent Teaching-Learning-based Optimization (TLO) algorithm to find the optimal network routing path between source and destination for Wireless Sensor Network (WSN). Compared with other routing metrics, the simulation results show that the proposed algorithm converged quickly and reached the optimal solution with minimal time and also improve the network performances.
