We study delay-efficient data aggregation scheduling in wireless sensor networks subject to signal to interference-plus-noise ratio (SINR) constraints. We construct a routing tree and propose two scheduling algorithms that can generate collision-free link schedules for data aggregation. We prove that the delay of each algorithm is $(O(R+\Delta ))$ time slots, where $(R)$ and $(\Delta)$ are respectively...
In traditional analysis to the performance of MBSFN uncorrelated shadow fading is used. In some cases this assumption does not capture the behaviors of the shadow fading. In this paper, a novel analytical model of system, user equipment receiver and correlated shadow are proposed firstly, then the performance measures were introduced, the changes in coverage due to correlation among the received signal...
