2017 IEEE International Conference on Intelligent Techniques in Control, Optimization & Signal Processing, Mar. 23 – 25, 2017, Srivilliputtur, INDIA Communication power analysis of applying MQV Key agreement scheme for wireless sensor network Qasem Abu Al-Haija Ghandi F. Manasra Mashhoor Al Tarayrah Department of Electrical Engineering, King Faisal University, Al-Ahsa, 31982, P.O. Box 400, Saudi Arabia Abstract— in this paper, we are analyzing the amount of communication power consumed from applying MQV key agreement protocol for wireless sensor network. The estimated power outcomes that exhibits the amount of communication power consumption is largely to be affected by the bit length of shared secret key recording. Valid and comparable results range from 1.6 μj to 51 μj for key sizes from 8-to-256 bits, for two neighboring sensor nodes is been achieved. In addition, these numbers usually increase when the number of neighbor nodes and communication distance increases. Keywords—Wireless Sensor Networks (WSN), Public key agreement, MQV scheme, Power consumption. I. INTRODUCTION In recent years, advanced synthesis and design have been achieved in the development of low cost, low power of multiprocessors sensor nodes with specific applications that has the power of communicating wirelessly. Such nodes are considered as wireless sensor networks (WSNs). This is possible because of the great achievements in advances of micro electro-mechanical systems (MEMS) technologies and digital electronics networks as well as advances in wireless communication systems [1,2,3]. The small size and the ability of these limited in size processor nodes, data processing, and communicating, make it possible to the building and designing of wireless sensor networks (WSNs) based on the joint effort of a large number of such wireless sensing nodes. WSNs are used as an area monitoring, where the WSN are deployed over a region where some phenomenon is to be monitored. For this, the development of these wireless sensor networks has been motivated by many researchers. Various applications are mainly focused towards military applications such as battlefield monitoring. In addition, these networks have been also used in industrial and as well as other related applications, such as industrial process control and giving constructive feedback for the sustainability of such process. Other systems of these WSNs are directed toward the building of devices used for health monitoring, and many other civilian type applications. The general network structure of WSNs is not usually limited to one design structure. For this, WSNs are built of various size nodes ranges from small number to several hundreds or even thousands of these nodes. In this sense, each ode can be hooked to one or more other sensor nodes. The design of such sensor network nodes should include few parts. These components should include a radio transceiver internal antenna or a connection to external antenna, as well as a microcontroller. For proper functionality of these nodes, one must design an electronic network that is compatible for interfacing with the sensors and other source of energy. The energy sources can battery type or if possible, an internally form of energy harvesting power type source. The ssize and design constraints on sensor nodes affects the functionality of the process such as energy, memory required, computational speed and the proper communications bandwidth. This can make the design of such WSNs nodes to be simple network to an advanced wireless multi directional communication network [4,5]. For efficient WSNs to be of effective use, one has to consider security threats that can be very crucial in many scenarios. The effect of disregarding such issues can be very harmful and causing serious problems to social life in general especially for applications that requires using of such wireless sensor networks [6]. Any WSN system must be coped with the power consumption constraint as well as its ability with possible other nodes failure and to be able to operate under harsh environment conditions. For this, the design of WSNs is a real challenging problem where one must consider the constraints imposed on power usage of such WSNs as we need to use such limited power for as long time as possible. This becomes important when it is usually cost prohibitive to replace damaged or exhausted batteries in a hostile environment or in places where it is hard to get an access to the node of the WSN [7]. In this work, we will focus on communication power consumed for key sizes from 8 – 256 bits for two neighboring these WSN nodes. The paper is designed to prolong the network lifetime, and to use energy-efficient and securely protocols. A newly distributed energy-efficient with proper security clustering scheme for homogeneous wireless sensor networks is proposed and evaluated. The organization of the paper will follow as in the next section, related work will be presented in section 2. Then, in section 3, problem formulation & modelling will be discusses and analyzed for MQV scheme. We will discuss and make our analysis of results regarding power consumption in section 4. Finally, in the last section 5 concluding remarks and future work will be presented. II. RELATED WORK Many researchers have investigated the security constraints of using effective WSNs [8, 9] and concluded that
