Abstract:
Wireless Sensor Networks (WSNs) consist of thousands of small nodes having
the capability of sensing, computation, and wireless communication. Many routing,
power management and data dissemination protocols have been particularly designed for
WSNs where energy utilization is an essential design issue. Since wireless sensor
network protocols are application specific, therefore the focus has been given to the
routing protocols that might be different depending on the application and network
architecture.
Over the recent years, one of the most important problems in wireless sensor
networks (WSNs) is to develop an energy-efficient and reliable routing protocol and
provide network robustness. To achieve these objectives, we propose a new data
dissemination protocol called Two Tier Cluster Based Routing Protocol (TTCRP) for
reliable data delivery in WSNs. TTCRP uses resource rich cluster heads with dual
channels to form the clusters for efficient data delivery. While it provides power control
algorithm to connect the isolated low power sensor nodes with minimum required power
that achieves the network robustness. Simulation results reveal that TTCRP is efficient
and provides reliability in both uniform as well as non-uniform sensor nodes deployment
