Green cellular networks based on accumulation with accumulative broadcast algorithms

This paper considers multi-hop cellular networks in which nodes use accumulation for cooperative broadcasting in order to save total energy with low delay. Our purpose is to build up Green Cellular Networks (GCN) which represent the trend of Next-Generation Networking (NGN) and cater for people´s demand for health and energy savings. Therefore, we assume a radiation and harmful region and show that power is in direct proportion to the area of the region so that we can focus on the power property. We also propose Virtual Tree (VT) to determine hop number in order to evaluate delay property of accumulative routing algorithms. Then, we propose a centralized broadcast routing algorithm specific for the asymmetric cellular based on accumulation named Cellular Accumulative Broadcast (CAB) Algorithm, which aims to realize low-delay minimum-energy broadcast. Further, we figure out the accumulative relay region for better analysis of relay cooperation. Simulation results show that our CAB algorithm performs superior to other existing accumulative or non-accumulative broadcast algorithms, which means GCN built up with CAB could be cost-effective with low delay.
