Wireless sensor networks (WSN) consist of small

self-contained devices with computational, sensing and wireless

communication capabilities. They allow flexible, powerful, tetherless,

automated data collection and monitoring systems to be

created. Anticipated applications include environmental hazard

monitoring, forest fire detection, machine instrumentation, etc.

Many routing protocols have been proposed to facilitate data

transport from sensor nodes to a base station few of these protocols

have been formally verified or operationally deployed however.

The Minimum Cost Forwarding (MCF) routing protocol[1],

has been proposed. The application of MCF is restricted to

networks possessing a single sink node and multiple source

nodes.-Wireless sensor networks (WSN) consist of small
