Improving energy efficiency is the most important challenge in wireless sensor networks. Because sensing information is correlated\r\nin many sensor network applications, some previous works have proposed ideas that reduce the energy consumption of the\r\nnetwork by exploiting the spatial correlation between sensed information. In this paper, we propose a distributed data compression\r\nframework that exploits the broadcasting characteristic of the wireless medium to improve energy efficiency. We analyze the\r\nperformance of the proposed framework numerically and compare it with the performance of previous works using simulation.\r\nThe proposed scheme performs better when the sensing information is correlated.
