Wireless Sensor Networks (WSNs) have emerged as a promising solution for variety of applications. Recently, in order to increase the lifetime of the network, many proposals have introduced the use of Mobile Elements (MEs) as a mechanical carrier to collect data. In this paper, the authors investigate the problem of designing the mobile element tour to visit subset of the nodes, termed as caching points, where the length of the mobile element tour is bounded by pre-determined length.
