In the following paper, we study the tradeoff between network lifetime and network utility for energy-constrained wireless sensor networks (WSNs) with the real-time requirement. By introducing a parameter r, we combine these two objectives into a single weighted objective, and consider rate control and routing in this tradeoff framework simultaneously. For real-time requirement, we set up real-time...
This paper describes a TDMA channel scheduling algorithm in WIA-PA network under the Blacklist technology (Blacklist-TCS). The main objective of this channel scheduling algorithm is to reduce the computation time while maximizing the utilization of the network resources, thereby improving the network throughput, reducing the transmission delay, and decreasing the number of retry. In this paper, we...
We consider the problem of finding an optimal and adaptive timeslot scheduling algorithm for long cycle data in WIA-PA network (ATS-LCD), which focuses on hybrid mesh and star network topology and a feedback mechanism that can significantly reduce collisions among clusters. OPNET simulation results demonstrate that ATS-LCD significantly outperforms TDMA-over-CDMA and CSMA MAC protocols in terms of...
