[Program doc] ssd2015 DL : 0: The aim of the present work is to develop a new Convergecast routing technique which allows to connect many source nodes to a single sink node via a wireless sensor network (WSN). The synthesized method overcame the problem of energy consumption resulting the repetition of the course of the edges during a transmission period. The proposed technique, based on intelligent routing algorithm to transmit the collected data to the base station, ensured a reduction of the routing paths length. This new approach was applied to a WSN, designed to control the temperature and volume of propane and butane in the tanks of the British Gas Group, for minimizing the energy consumed and increasing the life cycle of the network. Index Terms—Convergecast routing technique,Wireless Sensor Network WSN, Reduction of routing paths length, Minimization of energy consumption, Elongation of the life cycle.-The aim of the present work is to develop a new Convergecast routing technique which allows to connect many source nodes to a single sink node via a wireless sensor network (WSN).

[Program doc] FuzzyPSO_2010-(1) DL : 0: A Fuzzy-Particle Swarm Optimization Based Algorithm for Solving Shortest Path Problem. Abstract—In this paper, an efficient particle swarm optimization (PSO) algorithm based on fuzzy logic for solving the single source shortest path problem (SPP) is proposed. A particle encoding/decoding scheme has been devised for particle-representation of the SPP parameters, which is free of the previously randomized path construction methods in computational problems like the SPP .The search capability of PSO is diversified by hybridizing the PSO with fuzzy logic. The local optimums will not be the point of convergence for the particles and the global optimum will be found in a shorter period of time if the PSO is correctly modified using fuzzy logic rules. Numerical computation results on several networks with random weights illustrate the efficiency of the proposed method for computation of the shortest paths in networks
