Wireless sensor network(WSN) contains a number of sensor nodes distributed in the sensor field. Sensor nodes gather information from the environment, process them and then transmit data to the sink node. To send data from the source node to sink node require efficient routing algorithm. This routing algorithm plays important role in WSN is to finding a reliable path for a data transmission in the...
Underwater Wireless Sensor Network (UWSN) is emerging lots of attention due to its various types of characteristics and applications. Distinctive underwater characteristics leads to many challenges such as-high propagation delay, data losses, nodes mobility, localization, nodes deployment while designing any reliable and efficient routing protocol.

Wireless sensor networks are spatially distributed network of autonomous nodes that are used in the monitoring of physical and environmental conditions. Since these sensors have limited energy to work with, their storage and processing capabilities are very much basic. They also have very limited transmission range. Recent approaches have seen immense investments using WSN that demands sensor networks...
A wireless sensor network is a group of devices that uses radio to monitoring and sensing physical or environmental conditions at different location. Commonly monitored parameters are pressure, temperature, humidity, wind direction and speed, sound intensity, power-line voltage, and chemical concentrations. However, Energy efficiency is an essential design issue is a challenging task. In this simulation...
Wireless Sensor Network (WSN) is getting famous by its implementation and research exponentially in current time. Sensors can be configured on the basis of condition & when condition matches to the sensor then sensor collects some information. This information is transferred to the base station (BS). The data routing is performed by routing protocols. There are various types of routing protocols...
The contribution of this article is two local recovery methods that may reduce overhead and make a more immediate reconnection of disconnected nodes compared to the soft state global recovery method applied in WSNs running RPL [1]. In addition, we perform an analysis of the implication to better judge the context where local recovery methods should be used. One of our suggested methods is based on...
The devices composing Wireless Sensor Networks (WSN) are very limited in terms of memory, processing power and battery. We need efficient routing algorithms to ensure a long lifetime of the WSN. However, many solutions focus on minimizing the average energy consumption of all the nodes. Since the lifetime is rather given by the death of the first node or by the disconnection of the network, these...
Wireless Sensor Network (WSN) requires robust but simple, scalable, energy efficient and also self-configurable routing algorithms due to limited power of sensor nodes that are distributed in a large geographical area.

Reliability and timeliness are two essential requirements of successful detection of critical events in Wireless Sensor Networks (WSNs). The base station (BS) is particularly interested about reliable and timely collection of data sent by the nodes close to the ongoing event, and at that time, the data sent by other nodes have little importance. In this paper, we propose Congestion and Delay Aware...
Routing is an important issue in WSNs with the sensor nodes having limited processing power, memory etc. In this paper we present a query-based routing protocol for a WSN that provides different classes of Quality of Service (QoS) in terms of energy-efficiency, reliability, low latency and fault tolerance for different application requirements. The algorithm has low computational overhead while guaranteeing...
Inter-cluster communication technique is drawing immense research interest in recent wireless sensor network (WSN) applications. Since sensor nodes are very much constrained in power supply, extending lifetime of these sensors is essential. On the other hand, it is difficult to provide reliable data transfer in WSNs because of their unreliable link quality and congestion at a cluster head (CH) node...
In wireless sensor networks (WSNs), multi-path routing can find multiple paths from source node to sink node. In data transmission, multiple paths can be used to improve reliability, energy-efficiency, etc. In the literature, there have been many works about multi-path routing. But those multi-path routing protocols are not efficient as they cost much time and energy to construct multiple paths. In...

Throughput and energy efficiency are two important parameters to evaluate the performance of a wireless sensor network (WSN). For WSNs involved in varying channel conditions packet transmission reliability can be affected.
