Markov Model for Reliable Packet Delivery in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are the topic of intense academic and industrial studies. Research is mainly focused on energy saving schemes to increase the lifetime of these networks. There is an exciting new wave in sensor applications - wireless sensor networking - which enables sensors and actuators to be deployed independent of costs and physical constraints of wiring. For a wireless sensor network to deliver real world benefits, it must support the following requirements in deployment: scalability, reliability, responsiveness, power efficiency and mobility. The complex inter-relationships between these characteristics are a balance; if they are not managed properly, the network can suffer from overhead that negates its applicability.
