The main goals of this textbook are to introduce the concepts of space, time,frequency diversity, and MIMO techniques that form the foundation of cooperativecommunications, to present the basic principles of cooperative communicationsand networking, and to cover a broad range of fundamental topics w[r]

Due to the battery resource constraint, it is a critical issue to save energy in wireless sensor networks, particularly in large sensor networks. One possible solution is to deploy multiple sink nodes simultaneously. In this paper, we propose a protocol called MRMS (Multipath Routing in large scale[r]
