Maximizing Rewards in Wireless Networks with Energy - 2010

ABSTRACT:

Power efficiency is an important style issue in mobile devices with restricted power supplies. In this paper, we tend to study a souvenir-based mostly packet scheduling problem in wireless environments. We tend to contemplate a general scenario in which a transmitter Communicates with multiple receivers periodically. To guarantee timely transmission of knowledge, each packet is related to a delay constraint. The periodic knowledge streams have different importance levels, power functions, and levels of information sizes. The a lot of knowledge a transmitter delivers the more rewards it obtains. Our objective is to develop schemes that selectively transmit information streams of different data sizes at completely different transmission rates thus that the system reward will be maximized below given time and energy constraints. We tend to show that the matter is NP-exhausting and develop a dynamic programming algorithm for the optimal answer in pseudopolynomial time. A fast polynomial-time heuristic approach primarily based on clustering of states in state house is presented to realize close approximation. Simulation results demonstrate the effectiveness of the optimal solution and show that the proposed polynomial-time approach will achieve close to-optimal results. Both approaches build a significant improvement over other approaches adapted from existing studies Sat a marginal runtime overhead.
