Campbell Department of Electrical Engineering and Center for Telecommunications Research Columbia University NY 10027 USA Email campbell@ Recent advances in integrated circuits and in digital wireless communication technologies have enabled the design of wireless sensor networks WSN to facilitate the joint processing of spatially and temporally distributed information. Such networks immensely enhance our ability to understand and evaluate complex systems and environments. Using wireless connections for sensor networks offers increased flexibility in deployment and reconfiguration of the networks and reduces infrastructure cost. These advantages enable WSN applications in areas ranging from battlefield surveillance to environment monitoring and control to telemedicine. Enormous challenges in the understanding of sensor networks presently impede deployment of many of the envisaged applications. In particular for WSN that employ in situ unattended sensors physical constraints including those of power bandwidth and cost have presented significant challenges as well as research opportunities in the field. Of particular interest to this special issue are topics related to the communications and networking aspects of WSN. Indeed one of the major concerns in sensor networks is maintaining connectivity and networking functions with geographically dispersed sensor nodes under stringent resource .
