ENHANCEMENT CO-OPERATION OF MANET OF OPTIMAL MULTICAST USING BACKBONE GROUP MODEL
Publication Date : 26/02/2016
Many works have been conducted to investigate the improvement by introducing different kinds of mobility into the network. Other works attempt to improve capacity by introducing base stations as infrastructure support. This project gives a global perspective of multicast capacity and delay analysis in Mobile Ad Hoc Networks (MANETs). Specifically, this project considers four node mobility models: Two-dimensional i.i.d. mobility, Two-dimensional hybrid random walk, One-dimensional i.i.d. mobility and One-dimensional hybrid random walk. Two mobility time-scales are investigated in this project: fast mobility where node mobility is at the same time-scale as data transmissions and slow mobility where node mobility is assumed to occur at a much slower time-scale than data transmissions. Given a delay constraint D, the optimal multicast capacity for each of the eight types of mobility models are first characterized, and then a scheme is developed that can achieve a capacity-delay tradeoff close to the upper bound up to a logarithmic factor. In addition, this project also studies heterogeneous networks with infrastructure support.
