Optimal Capacity-Delay Tradeoff in MANETs With Correlation of Node Mobility

In this paper, we analyze the capacity and delay in mobile ad hoc networks (MANETs) considering the correlation of node mobility (correlated mobility). Previous works on correlated mobility investigated the maximum capacity with the corresponding delay in several sub-case, the problem of optimal capacity under various delay constraints (the optimal capacitydelay tradeoff) still remains open. To this end, we deeply explore the characteristics of correlated mobility, and figure out the fundamental relationships between the network performance and scheduling parameters. Based on that we establish the overall upper bound of capacity-delay tradeoff in all the sub-case of correlated mobility. Then we try to obtain the achievable lower bound by identifying the optimal scheduling parameters on certain constrains. Results demonstrates the whole picture of how the correlation of node mobility impacts the capacity, delay and the corresponding tradeoff between them.
