Rate Allocation and Network Lifetime Problems for Wireless Sensor Networks
White Papers Since the objective of maximizing the sum of rates of all the nodes in the network can lead to a severe bias in rate allocation among the nodes, it advocates the use of Lexicographical Max-Min (LMM) rate allocation.
