A routing protocol with energy and traffic balance awareness in wireless ad hoc networks

The work of this paper is motivated by the idea of taking account of several factors in wireless mobile ad hoc networks ( MANETs ) routing design in a unified way. The rational of our motivation is that most of the routing protocols is designed only based on one criteria, e.g., shortest path considered, or power conservation. There are few works which could consider several factors in a unified way at the same time. Therefore, we propose a routing scheme which could consider power conservation, shortest path and traffic load balancing, named power and traffic balance awareness paths selection routing scheme ( PTPSR ). In this routing scheme, we would consider both the shortest path and the power conservation in an unified way. We define an energy factor as the ratio of the remaining energy over the initial energy of a node. We will use the products of the energy factors of all the nodes along different paths as the selection criteria. The higher the products of all the energy factors, the higher the remaining energy they will have, in the mean time, the higher the products of the energy factors, the fewer the number of hops along the path. We conduct simulation in Glomosim to compare the PTPSR with other routing protocols, e.g., ad hoc on demand multi-path distance vector (AOMDV). The results demonstrate that PTPSR would achieve better performance.
