This paper proposes an algorithm to determine a mobile sink trajectory to cover the entire target area in a timely manner and dissemination of data with lesser delay. The proposed algorithm is based on Hilbert Space Filling Curve algorithm with dynamic control of graph order according to network density. The simulation results show that by overlaying(More)
In post disaster situations it is vital to restore voice and data communication services quickly. Currently, portable wireless systems are used as a temporary solution. However, these solutions have a lengthy setup, limited coverage, and typically require the use of expensive satellite backhaul. Solutions based on cognitive radio mesh networks have been(More)
Cellular coverage is often a challenge in low population density and low income rural areas of the developing world like Tanzania. This is because big Telecom companies defer from deploying their expensive infrastructure in these areas fearing operations cost. It is proposed that the use of cellular open source technology as the basis for a new rural(More)
