摘 要：The ad hoc networking is an ultimate technology in wireless communication that allows wireless devices located within their transmission range to communicate directly to each other without the need for established fixed network infrastructure. It is a new area of research that has become extremely popular over the last decade and is rapidly increasing its advance into different areas of technology. In this paper1 properties, limitations and basic issues related to development of wireless sensor network applications are investigated. The focus is on reliable and energy aware inter-node communication strategies. The approaches to power control and activity control of nodes axe briefly summarized. The results of the performance evaluation of energy aware protocols through simulation are presented and discussed. The protocol that relies on hierarchical routing and uses a periodic coordination for energy efficient WSN is described and investigated.
