On the Throughput-Delay Tradeoff in Georouting Networks - 2016


We study the scaling properties of a georouting theme in a very wireless multi-hop network of n mobile nodes. Our aim is to extend the network capability quasi-linearly with n, while keeping the common delay bounded. In our model, we tend to contemplate mobile nodes moving consistent with an independent identically distributed random walk with velocity v and transmitting packets to randomly chosen fixed and known destinations. The average packet delivery delay of our scheme is of order one/v, and it achieves network capability of order (n/log n log logn). This shows a practical throughput-delay tradeoff, in particular in comparison with the seminal result of Gupta and Kumar, which shows network capacity of order (n/log n)1/a pair of and negligible delay and the groundbreaking results of Grossglauser and Tse, which achieves network capability of order n but with an average delay of order vn/v. The foundation of our improved capability and delay tradeoff relies on the fact that we use a mobility model that contains straight-line segments, a model that we tend to contemplate more realistic than classic Brownian motions. We tend to ensure the generality of our analytical results using simulations beneath varied interference models.
