A Mobile Wireless Sensor Network (M-WSN) derives its name by considering either mobile sink or mobile sensor nodes within the Wireless Sensor Network (WSN). As the sensor nodes are energy constrained, energy efficiency is the main aspect to be considered in any applications. By considering mobile sensor nodes in WSN, we can have better energy efficiency, improved coverage, and enhanced target t...

Minimizing Energy consumption is considered as one of the most important principles in the development of routing protocols for Wireless Sensor Networks (WSN). In this study, we propose a Location based Energy-Aware Reliable routing protocol (LEAR) for WSN based on sensor position and clustering. Geographical routing protocols are efficient and convenient for optimum energy consumption and band...

Recent breakthroughs in micro sensor technologies allow us to engineer compact, battery powered, wireless communication enabled and cheap sensing devices, sensor nodes. Combining those cheap sensor nodes into networks allows us to create Wireless Sensor Networks (WSN). Figure.1 shows the general architecture of a typical WSN. Sensor nodes are usually low power, with limited computational and st...

A wireless sensor network (WSN) consists of many tiny and low-power devices deployed in a sensing field. One of the major tasks of a WSN is to monitor the surrounding environment and to detect events occurring in the sensing field. Given an event appearing in a WSN, the event detection latency is to model the time that it takes for the WSN to be aware of the event. In this work, we analyze the ...

Since the data collected by the nodes of WSN are sensitive and vulnerable to attack, there’s a need of making the Wireless Sensor Networks (WSN) immune to attacks. Most of the researchers have come up with security solution to WSN based on layered approach. Layered approach has noticeable flaws like ‘redundant’ security or ‘inflexible’ security solutions. In this paper a new security scheme is ...

Wireless Sensor Networks (WSNs) have been promised a bright future and economic potential. Since the vision of ’Smart Dust’, the field has largely progressed: Miniaturization, integration and advances in MEMS technology have significantly stimulated research efforts. While there has been a lot of progress in theoretical work and system optimizations, actual deployments have been nonor underperf...

Time synchronization is of primary importance for the operation of wireless sensor networks (WSN): time measurements, coordinated actions and event ordering require common time on WSN nodes. Due to intrinsic energy limitations of wireless networks there is a need for new energy-efficient time synchronization solutions, different from the ones that have been developed for wired networks. In this...

Sensor nodes are being increasingly deployed for monitoring different phenomena in a stand-alone manner or as a part of larger wireless sensor networks (WSN). In addition to protocols for communication within the WSN, sensor nodes may also support communication with other devices. These devices either represent gateways for exposing data and metadata to external networks, or serve as connection...

Routing protocol in wireless sensor network (WSN) has always been a frequently adopted topic of research in WSN owing to many unsolved issues in it. This paper discusses about the multicast routing protocols in WSN and briefs up different forms of standard research contribution as well as significant recent research techniques toward leveraging the performance of multicast routing. The paper th...

In multihop wireless sensor network (WSN) users or nodes are constantly entering and leaving the network. Classical techniques for network management and control are not conceived to efficiently face such challenges. New mechanisms are required, to work in a self-organized manner. The techniques found in nature promises WSN, to self-adapt the environmental changes and also self-protect itself f...
