Abstract

This paper presents a distributed N-to-1 multipath routing for Wireless Sensor Network (WSN) which addresses as a Multi-objective Optimization Problem (MOP), where three function was optimized with the aim to do an efficient use of the energy in the network and decrease the possibility of packet loss. These functions are: hop count, energy consumption, and free space loss. The simultaneous optimization of these three functions is a NP-complete problem and intends to use a software implementation of Multi-Objective Evolutionary Algorithms (MOEA), specifically the Strength Pareto Evolutionary Algorithm (SPEA2) to solve it.
