Metaheuristics for the deployment problem of WSN: A review

The deployment problem (DP) of a wireless sensor network (WSN) is no doubt a critical issue because the strategies it takes will not only strongly impact the overall performance but also the power consumed by the sensors in such a system. This means that a good solution to the deployment problem (DP) cannot just “enhance its performance,” it can also “save the energy” to prolong the lifetime of a wireless sensor network (WSN). However, finding an optimum solution for most DPs with limited computation resources is still a challenging research problem, especially for the NP-hard optimization problems. Compared to exhaustive search and deterministic algorithms, metaheuristics provides an alternative way to solve these optimization problems, by looking for a near optimal solution using limited computation resources within a reasonable time. Aimed at providing not only a systematic survey of metaheuristics for solving the deployment problem but also a roadmap for researchers working on WSN and metaheuristics to further develop and improve a wireless sensor network system, this paper begins with an overview of WSN and the deployment problem, followed by discussions on metaheuristics and how to use them to solve the DP. Then, a comprehensive comparison between metaheuristics for the DP is given. Finally, open issues and future trends of this field are addressed.

A Comparison of Link Layer Attacks on Wireless Sensor Networks

Wireless sensor networks (WSNs) have many potential applications [1, 5] and unique challenges. They usually consist of hundreds or thousands small sensor nodes such as MICA2, which operate autonomously; conditions such as cost, invisible deployment and many application domains, lead to small size and limited resources sensors [2]. WSNs are susceptible to many types of link layer attacks [1] and most of traditional networks security techniques are unusable on WSNs [2]; due to wireless and shared nature of communication channel, untrusted transmissions, deployment in open environments, unattended nature and limited resources [1]. So, security is a vital requirement for these networks; but we have to design a proper security mechanism that attends to WSN's constraints and requirements. In this paper, we focus on security of WSNs, divide it (the WSNs security) into four categories and will consider them, include: an overview of WSNs, security in WSNs, the threat model on WSNs, a wide variety of WSNs' link layer attacks and a comparison of them. This work enables us to identify the purpose and capabilities of the attackers; also, the goal and effects of the link layer attacks on WSNs are introduced. Also, this paper discusses known approaches of security detection and defensive mechanisms against the link layer attacks; this would enable it security managers to manage the link layer attacks of WSNs more effectively.

Overview of Wireless Sensor Networks: Detection of Cloned Node Using RM, LSN, SET, Bloom Filter and AICN Protocol and Comparing Their Performances

Sensor nodes deployed in hostile environments are vulnerable to capture and compromise. Due to the inexpensive hardware components, an attacker can easily obtain cryptographic information from these sensors, clone them and surreptitiously insert these clones back in the network. Cloning provides the adversary an easy way to build an army of malicious nodes that can cripple the sensor network. Therefore, the detection of cloned nodes is a fundamental problem of sensor network. However, sensor nodes are usually resource-constrained, which make security applications a challenging problem. At present, there are only a few clone detection protocols which are truly distributed and random in nature. In this paper, we review these protocols with their performances.
