An Inverse Problem In Wireless Mesh Network

The wireless mesh network technology has been studied extensively over the last few years. It can be deployed to provide the broadband Internet services in rural and geographically disadvantaged areas, due to the ability to enable the extended coverage. It also provides an alternative to the last mile broadband access. In this paper, we present a network performance analysis using the network tomography paradigm to estimate the end-to-end link performance of the information flows over the mesh networks. A network tomography base routing scheme Expectation-Maximization (EM) routing approach is proposed to estimate the network flow performance such as delay, which again can be used for routing optimization over the network to achieve desirable performance. We then compare the estimated results with the NS-2 simulations.
