In this paper, a communication load balanced dynamic topology management algorithm (CLB-AODV) is proposed to extend the wireless sensor network (WSN) lifetime via managing the participation in communication process among all nodes in the network. The idea is that, each time there is a failure in the network topology; the topology is adjusted only on-demand by choosing the best path according to paths...
WBAN is the limited version of the WSN. The area covered by network is the main constrained in the WBAN as compared to the WSN. Various routing protocols applicable in the WSN must have optimized performance in WBAN. This paper analyzes the performance of the various routing protocols of the wireless network in the WBAN and WSN. Moreover, the paper also compares their performance in the same network...
Wireless Sensor Network (WSN) is a collection of sensor nodes capable for sensing instantaneously. WSNs are widely deployed in hostile environment on ad-hoc basis. Routing protocols are used to discover a suitable route among sensor nodes and transfer sensed data from one node to another node. Several routing protocols are developed and configured according to their characteristics. Ad-hoc nature...
In the Wireless Sensor Networks (WSNs), limited energy resource is one of the limitations of the wireless sensor nodes. For the energy efficient packet transmission in the WSNs, we introduce a new algorithm called Finest Energy Efficient Routing (FEER) Algorithm. In this algorithm, the energy efficiency is achieved through the comparison of the energy of the neighbor nodes of the source. Initially,...
In wireless sensor network (WSN), data collecting from the environment and sending that data to be processed and evaluated is the most important issues. Hence performance evaluation and comparison between routing protocols is required because performance of any routing protocol can be changed or very with various parameters such as speed, seed time, pause time, number of node, and traffic scenario...
Wireless Sensor Network (WSN) is a group of spatially distributed sensor nodes and is self organized and autonomous in nature. They are connected by wireless links. Routing in wireless sensor network is quite different from traditional wireless network, due to limitations of wireless sensor network. To overcome some of the limitations, UDP is being used for connection establishment, compromising the...
Topology change is the main factor that affects the network life time of Wireless Sensor Network (WSN) applications. In static WSN, the topology change is often caused by node failure which is due to energy depletion. However, in the Mobile WSN (MWSN), the main reason of the topology change is caused by the node movement. Since the mobile sensor nodes are limited in power supply and have a low radio...
When the topology is mesh in ZigBee network, by changing the communication radius of the node, simulation result proves that the different effective communication distance of signal has a great influence on the network performance, meanwhile, the different values of key parameters MY_ROUTE_TIMEOUT and ACTIVE_ROUTE_TIMEOUT also cause some effect to the network performance. Through summarizing the simulation...
Sensor deployment is one of the key topics addressed in Wireless Sensor Network (WSN). This paper proposes a new deployment technique of sensor nodes for WSN called as Quasi Random Deployment (QRD). The novel approach to deploy sensor nodes in QRD fashion is to improve the energy efficiency of the WSN in order to increase the network life time and coverage. The QRD produces highly uniform coordinates...
Wireless Sensor Networks (WSNs) is an emerging field of engineering with various applications. They have emerged as a new class of large scale networks of embedded systems with limited communication, computation and energy resources. Recently adopted IEEE 802.15.4 standards for Low-rate Wireless Personal Area Network (LR-WPAN) are most extensively used communication platform for WSNs. Conventional...
As more and more real Wireless Sensor Network's (WSN) applications have been tested and deployed over the last decade, the research community of WSN realizes that several issues need to be revisited from practical angles, such as reliability and availability. Furthermore, fault-tolerance is one of the main issues in WSNs since it becomes critical in real deployed environments where network stability...
In a multi-hop wireless sensor network (WSN), the nodes that are one hop away from the Sink die first and cause an "energy hole," because they must forward the traffic from the rest of the network. When this hole forms, a large amount of "excess" energy is trapped in the other nodes. In this paper, we propose that some of those other nodes use some of the excess energy to do cooperative...

Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro-sensors to larger scale, controllable weather-sensing platforms. In order to simulate Wireless Sensor Networks (WSNs), we implemented a simulation...
This paper proposes an improved Ad-hoc On-Demand Distance Vector (AODV) routing protocol based on node-grade to reduce the energy consumption of nodes in wireless sensor networks. The improved AODV called Grade-AODV (G-AODV) assigns a grade to each node according to the hop distance of the node to the sink node. The lower grade a node has, the closer it is to the sink. Each node is restricted to receive...
Wireless Sensor Networks (WSNs) use tiny, inexpensive sensor nodes with several distinguishing characteristics: they have very low processing power and radio ranges, permit very low energy consumption and perform limited and specific monitoring and sensing functions. However, its security becomes an issue because in WSNs, there is virtual communication by passing the data through sensor via internet...
The traditional routing protocols for mobile ad hoc networks (MANET) are not appropriate for wireless sensor networks (WSNs). The reason is the large amount of overhead produced may exhaust the energy of the network and shorten its lifetime, especially in the process of maintaining routes. In this paper, considering a large scale WSN, we propose a simple but efficient AODV-based protocol, called AODV...
With the development and wide application of WSN (Wireless Sensor Network), the information security becomes a serious problem, especially when the WSN applied in military field. Whereas the general WSN routing protocols focus on the transmission efficiency, reliability and energy-efficiency, not on the security. This paper integrates the international popular AES encryption standard, RSA public-key...
The transmission power and the reception power are the main source of energy consumption in wireless sensor nodes. Therefore, reducing the amount of consumed power through the transmission and reception processes in the routing protocol will lead to an increase in the lifetime of the wireless sensor network and distribute the consumed power among the wireless sensor nodes. This paper proposes a mechanism...
