Localization of Nodes: A New Challenge for Wireless Sensor Networks
International Journal of Computer Applications, 2013
With the widespread involvement of low cost, small sized sensor nodes in the wireless sensor networks (WISENETs) technology to support variety of collaborative applications such as monitoring and surveillance for civilian as well as military purposes; location aware computing for such nodes is really becoming an important challenge. Localization also plays a vital role in ubiquitous environments with computing potentials in targeting nodes for their security as well as navigation. Since inclusion of GPS receiver in a sensor node becomes too expensive, hence for locating sensor nodes in wireless sensor networks a small number of sink nodes are used that know their location whereas other nodes estimate their location based on the transmission and receiving energy of the message which they send to the sink node. This paper provides an overview of the existing localization solutions with their comprehensive performance metrics in wireless sensor networks and attempt to classify them broadly in terms of their usage area which can be indoor or outdoor or both.

In wireless sensor networks (WSNs), nodes are deployed in sensor fields for monitoring and controlling the physical environments. Node localization is fundamental challenge in wireless sensor networks as without knowing the location of nodes sensed information will have no value. Therefore, it is vital that nodes must know their location. This paper provides a review of basic techniques for localization.

Localization algorithms of Wireless Sensor Networks: a survey
Telecommunication Systems
In Wireless Sensor Networks (WSNs), localization is one of the most important technologies since it plays a critical role in many applications, e.g., target tracking. If the users cannot obtain the accurate location information, the related applications cannot be accomplished. The main idea in most localization methods is that some deployed nodes (landmarks) with known coordinates (e.g., GPS-equipped nodes) transmit beacons with their coordinates in order to help other nodes localize themselves. In general, the main localization algorithms are classified into two categories: range-based and range-free. In this paper, we reclassify the localization algorithms with a new perspective based on the mobility state of landmarks and unknown nodes, and present a detailed analysis of the representative localization algorithms. Moreover, we compare the existing localization algorithms and analyze the future research directions for the localization algorithms in WSNs.

Localization Techniques for Wireless Sensor Networks: A Review
Wireless sensor networks (WSNs) have recently emerges as promising technology in wireless communication field and gained special attention by research groups. It uses small and cheap gadgets with low energy requirements and limited on board computing resourceswhich communicates with each other's or base stations without any pre-defined infrastructure. The property of being infrastructure less makes it suitable in distinctive application situations including remotemonitoring, disaster management, military applications and biomedical health observing devices. In many of these applications, node localization is unavoidably one of the important system parameters for example in target tracking if the nodes are not able to obtain the accurate location information, the related task cannot be performed.It is also helpful in routing, network coverage and quarry management of sensors. In general the localization techniques are ordered into two general classifications: range based and range free.
