Deployment of sensor nodes in underwater wireless sensor networks with a goal of maximum network field coverage is very difficult. Moreover, to access the information from sensor nodes efficiently in aquatic environment is very unpredictable. In our scheme sensor nodes are randomly deployed in the network filed. We have cover the maximum network field through constant mobility of two sinks. Due to...
Design of underwater wireless sensor networks (UWSNs) is difficult because of limited battery energy of sensor nodes. Low bandwidth and energy consumption are major problems that we face in UWSNs, due to dynamic behavior of water in underwater environment. In our scheme, circular field is divided into ten sub-regions and each region is divided into eight sectors. Two mobile sinks move to cover the...
In this paper, we propose a reliable and interference-aware routing protocol for underwater wireless sensor networks (UWSNs). Proposed protocol follows end-to-end path from source node to sink and selects next forwarder node of a data packet on the basis, having already established a path to sink. In this way, the problem of encounters void hole in depth based routing protocol is eliminated. Furthermore,...
This paper presents cooperative routing scheme to improve data reliability. The proposed protocol achieves its objectives, however, at the cost of surplus energy consumption. Thus sink mobility is introduced to minimize the energy consumption cost of nodes as it directly collects data from the network nodes at minimized communication distance.
In Underwater Wireless Sensor Networks (UWSNs) nodes are equipped with limited battery power and battery replacement is expensive due to underwater harsh environment. Therefore, we propose EBECRP an energy Efficient and Balanced Energy consumption Cluster based Routing Protocol for UWSNs. In depth base routing protocols nodes near the sink (low depth nodes) die in no time because of high load. We...
The unique characteristics of Underwater Wireless Sensor Networks (UWSNs) attracted the research community to explore different aspects of these networks. Routing is one of the most important and challenging function in UWSNs, for efficient data communication and longevity of sensor node's battery timing. Sensor nodes have energy constraint because replacing the batteries of sensor nodes is an expensive...
Underwater Wireless Sensor Networks (UWSNs) are getting growing interest because of wide-range of applications. Most applications of these networks demand reliable data delivery over longer period in an efficient and timely manner. However, resource-constrained nature of these networks makes routing in a harsh and unpredictable underwater environment challenging. Most existing schemes either employ...
