Though mobility is rarely considered in traditional wireless sensor networks (WSNs), actively exploiting mobility to improve the performance of WSNs has been increasingly recognized as an important aspect of designing WSNs. This chapter focuses on exploiting mobility to improve the network lifetime of a WSN. We present a general optimization framework that is able to capture several aspects of ...

Along with the fast development of sensor hardware, traditional scalar sensor nodes are now provided with both multimedia and mobility functions. By observing this emerging combination of these two functions into traditional wireless sensor networks (WSNs), we take the opportunity in this paper to highlight a subset of WSNs, which we name as “Mobile Multimedia Sensor Networks (MMSNs)”. Furtherm...

Wireless Sensor Networks (WSNs) have been widely considered as one of the most important technologies. This technology has introduced a new flux in diversified fields like medical, military, environment, home, agriculture, etc. Since the sensor nodes in WSN are battery operated hence energy awareness is one of the most important issues in WSNs. To achieve minimum energy consumption, several MAC...

Wireless Sensor Networks (WSN) have recently been extensively deployed and researched. They are composed of a high number of small and simple nodes where most of them have to function as a router in an ad hoc manner. Because of limited energy sources in sensor network node, routing protocols should save the energy as much as possible. Energy consumption has a direct influence on network lifetim...

Wireless Sensor Networks consist of small, low-power, low-energy nodes used for monitoring environmental parameters such as temperature, humidity and motion. Routing is a critical issue in WSN and hence the WSNs are required to provide different levels of Quality of Services (QoS) based on the type of applications. Due to resource constraints like processing power, memory, bandwidth and power s...

It is challenging to secure a wireless sensor network (WSN) because its inexpensive, tiny sensor nodes do not have the necessary processing capability, memory capacity, and battery life to take advantage of the existing security solutions for traditional networks. Existing security solutions for wireless sensor networks are mostly based on symmetric key cryptography with the assumption that sen...

Wireless Sensor Networks (WSNs) are universally being used and deployed to monitor the surrounding physical environments and detail events of interest. In wireless Sensor Networks energy is one of the primary issues and requires energy conservation of the sensor nodes, so that network lifetime can be maximized. To minimize the energy loss in dense WSNs a Color Based Topology Control (CBTC) algo...

A typical Wireless Sensor Network (WSN) consists of a sink node sometimes referred to as a Base Station and a number of small wireless sensor nodes. The base station is assumed to be secure with unlimited available energy while the sensor nodes are assumed to be unsecured with limited available energy. The sensor nodes monitor a geographical area and collect sensory information. Sensory informa...

With the widespread growth of applications of Wireless Sensor Networks (WSNs), the need for reliable security mechanisms these networks has increased manifold. Many security solutions have been proposed in the domain of WSN so far. These solutions are usually based on well-known cryptographic algorithms. In this paper, we have made an effort to survey well known security issues in WSNs and stud...

With the constant development of Wireless Sensor Networks (WSN), the problem of these networks has become gradually serious. People are beginning to study the performance analysis of WSNs.
