In this paper, we study end-to-end performance characteristics of S-MAC, an energy-aware medium access control (MAC) protocol for wireless sensor networks (WSN). WSNs are composed...
The main focus of this article is to achieve prolonged network lifetime with overall energy efficiency in wireless sensor networks through controlled utilization of limited energy...
Opportunistic activity and context recognition systems do not presume a static sensor infrastructure that is defined at the design time of a system. They also do not have a fixed ...
Abstract—Wireless sensor networks (WSNs) have been extensively researched recently. This paper makes two contributions to this field. First, we promote a new concept of long-thi...
