Abstract:

It is a theoretical basis to solve the lifetime maximization problem of designing energy-efficient routing or topology control protocols. Many approac hes focus on this problem and heuristic algorithms are proposed where the energy consumed by receiving data is not considered. In this paper, we define   the traffic planning and its corresponding lifetime of a sensor network, and then formulate the lifetime maximization problem. We propose two genetic coding methods and analyse their strengths and weaknesses.

Key words: （sensor network, maximum lifetime;genetic coding）
