Abstract

In this paper, we propose optimization algorithms for the problem of multiple mobile sinks route planning in Wireless Sensor Networks (WSN). Our aim is to reduce the length of the sink routes, in order to reduce the message delivery delay. Our approach differs from others in the literature since clustering and route planning are dealt simultaneously. We compare the proposed algorithms and the best of them are used to perform WSNs simulations. By comparing our approaches to others in the literature, significant gains in terms of message delivery delay rates are attained.
