Architectural and Management Schemes for Efficient Data Collection in Wireless Sensor Networks

In most applications of wireless sensor networks (WSNs), sensors are constrained in the amount of available energy and computation resources. Unlike traditional networks, protocols for sensor networks have to be designed with these constraints in mind. This paper proposes ARM, an ARchitectural and Management schemes for efficient data collection in WSNs. ARM employs a suite of distributed algorithms and pursues an integrated approach to network management. The sensor network is divided into cells to achieve scalability. The cells use a novel distributed medium arbitration scheme, which enables simultaneous collision-free data transmission. The predictable access allows nodes to stay in the sleep mode for the longest possible time and thus minimizes energy consumption
