Cross-layer models are becoming popular in various wireless networking domains due to their realistic predictions and for fundamental understanding of the interaction between adjacent networking layers. A combined PHY/MAC layer energy consumption model is considered here for short range IEEE 802.15.4 networks for non-beacon-enable mode in case of dual hop transmission under Rayleigh fading channel...
The early success of wireless sensor networks has led to a new generation of increasingly sophisticated sensor network applications, such as HP’s CeNSE. These applications demand high network throughput that easily exceeds the capability of the low-power 802.15.4 radios most commonly used in today’s sensor nodes. To address this issue, this paper investigates an energy-efficient approach to supplementing...
In this paper, we analyze an IEEE 802.15.4-compliant wireless sensor network, organized in clusters with fusion centers (FCs) acting as cluster heads. Sensors observe the same common binary phenomenon, decide on its status, and send their decisions to the FCs, which perform a majority fusion. FCs' decisions are then sent to an access point, where a final estimate is obtained. Data aggregation (DA)...
The delay sensitive industrial control applications like Industrial process control, Environmental control, Gas leakage monitoring, etc. in this a reliable communication between sensor and base station are highly essential. Wireless Sensor Networks (WSN) becomes an immensely popular technology in such application as it offers low latency and high energy-efficiency in message transmission. Life span...
