This paper investigates the issue of target-barrier coverage in wireless sensor networks that utilize both static and mobile sensors, resulting in enhanced fault tolerance and reliability. The main objective is to establish a reliable and dependable protective barrier around the target and detect any intrusion within its perimeter. The introduction of distance limits, namely boundlow and boundup, can ensure that the constructed barrier provides sufficient response time to report detected intrusions. This methodology is particularly well-suited for applications that demand high levels of dependability and fault tolerance, such as battlefield monitoring and intruder detection. Furthermore, by introducing mobile sensors in conjunction with static sensors, it will help increase the success rate of target-barrier construction and reduce the number of required scattered static sensors. Experimental simulations validate the proposed method and illustrate that it offers superior network lifetime compared to alternative approaches, while maintaining high levels of fault tolerance and reliability.

In the present scenario, there are substantial amount of application where mobile wireless sensor network (MWSN) would be better choice over the static wireless sensor network. The very nature of the MWSN environment requires sensor nodes to interact opportunistically to address a common goal. coverage is one of those areas where MWSN provides better solution. coverage in static WSN depends on the initial deployment strategy. Most of the recent works in MWSN propose re-deployment strategy with the help of mobile nodes. In MWSN, the mobility of sensor nodes can be utilized to enhance the coverage of the network. One of the fundamental problems of MWSN is how to coordinate these mobile sensors in such a way that they can move together to accomplish the given task. Here, we study a generalized case of this problem. In this paper, we present a coordination based motion control (CBMC) scheme where all mobile nodes form a cooperative group such that they cover an area by exchanging some key information between themselves. The proposed scheme has two objectives: (i) each sensor node travels a minimum distance;(ii) minimum overlap in the coverage path of sensor nodes. NS-3 simulation shows the effectiveness of CBMC scheme. The proposed scheme is compared with random way-point mobility model (RWP) and three other variants of RWP.

Wireless sensors networks are active area for research and a broad platform for many commercial applications. coverage in a wireless sensor network can be thought of as how well the wireless sensor network is able to monitor a particular field of interest. Ensuring sufficient coverage in a sensor network is essential to obtaining valid data. In this paper coverage strategies are studied which are used in deployment stage. Strategies are categorized into three groups;Force Based, Grid Based and Computational Geometry Based Approach. In this paper Delaunay Triangulation computational geometry coverage strategy is implemented using MATLAB. It is found that Delaunay triangulation coverage strategy is efficient coverage strategy.
