Load balancing is a crucial problem in mobile ad hoc networks. Many conventional routing protocols that are developed are not having functionality of coping up load balancing. Hence several kinds of approaches are followed in the design and development of load balancing routing protocols. This paper aims to survey research articles pertaining to load balancing research problem in mobile ad hoc networks. Here various approaches are taken into account and literatures' key ideas are presented.

Abstract-This paper studies the applicability of hybridization of Differential Evolution (DE) and PSO techniques to data clustering problem. A new way of integrating DE and PSO is explored in the paper. In one approach, a parallel DE and PSO developed and in other, a transitional approach of alternate DE and PSO technique followed. Simulations for number of data sets show that the proposed integrated approach provides better clustering performance.
