Temporary Cluster Based Routing for Underwater Wireless Sensor Networks

摘要

During the last couple of decades Underwater Wireless Sensor Networks (UWSN) have attracted more attention for ocean monitoring systems. Due to adverse environment, UWSN face many problems like bandwidth limitations, high error probability, node movements and 3-dimensional space and with such challenges, we need a robust and scalable architecture for providing a self configuring network of distributed nodes. In order to handle the problem of large propagation delays and unreliable link quality, many authors proposed multi-hop data delivery routing schemes. But, such multi-hop routing protocols drain more energy of the nodes near the sink. In this paper, we proposed a mobility aware routing protocol, called "Temporary Cluster Based Routing" which not only requires equal energy consumption for all the nodes throughout the network but also it helps to save energy, as it prefers to send the sensed data over short distances. Moreover, it does not require any location information of sensor nodes and only a small number of nodes are involved during the end-to-end routing process. This makes it suitable not only for stationary and mobile networks but for the hybrid networks as well.
