Joint Maximum Lifetime and Robust Routing for Wireless Sensor Networks
Since the energy constraint is a fundamental issue for wireless sensor networks (WSNs),the expectation of network lifetime has become a critical performance index.In actual applications,due to the data traffics may fluctuate randomly,there is a compelling need for a routing strategy that is robust to the variation amplitude of time varied data traffics.In this paper,we jointly consider the lifetime maximization and a routing strategy with robustness,both of which are in compliance with the framework of cross-layer optimization.These two correlated subproblems can be further modeled as a nonlinear optimization problem.By using the risk measures defined in the financial mathematics,the proposed optimization problem can be relaxed while the non-convex constraint can be transformed into a solvable expression.Extensive Simulation results are further provided to validate our robust routing proposal.
