Fundamentals of Mobile and Pervasive Computing

Chapter 11Approaches and Solutions

In previous chapters we have considered a number of challenges to using ad hoc networks, in particular wireless sensor networks. As we discussed earlier, large-scale deployment of wireless sensor networks has become feasible only recently. Until recently, the cost of these nodes was too high, the size of sensor nodes was too large, and the capabilities for sensing and computation were too limited for many applications. Because wireless sensor networks became broadly applicable only a short time ago, the protocols for using sensor nodes and networking them together efficiently are relatively new. Although the protocols will continue to improve and new ideas will be developed, we can recognize a number of general ...
