management is one of the most important issues of any secure communication with the increasing demand for the security in wireless sensor networks (WSNs) it is important to introduce the secure and reliable key management in the WSNs.Data confidentiality and authenticity are critical in WSNs. Key management objective is to secure and keep up secure connections between sensor nodes at network formation and running stages. In this paper we proposed various key management schemes, necessity for key management

Overview Sensors are used for myriad applications, from measuring and controlling the temperature in buildings to helping motorists park their cars. The military is one of the biggest users of sensors, which have become so sophisticated that they can be used to help detect enemies in the air, the ground and the water. The demand is increasing for automation, safety & control devices as users now demand more safe solutions. Demand for automation & sensing products is increasing even under difficult

few years wireless sensor networks (WSN’s) have gained global attention. It is a promising technology that has been extensively used in various critical and long-lasting applications. A Wireless Sensor Network (WSN) has a large number of energy constrained sensor nodes that have the capability to compute and communicate. They are used to identify the events of interests and transfer the data to the sink node. WSN is categorized into fixed WSN and mobile WSN. Target area has fixed sensors for performing

Wireless Sensor networks are defined as the distribution of the sensors in the irregular manner. It is a heterogeneous system. The range of sensors used in the network may be from few hundreds to thousands. These sensors will have limited resources like power, storage, communication and processing capability. The security requirements of WSN can be the following they are • Confidentiality • Integrity • Authentication • Availability • Key establishment and trust setup • Freshness • Resilience

INTRODUCTION A Wireless Sensor Network or WSN is supposed to be made up of a large number of sensors and at least one base station. The sensors are autonomous small devices with several constraints like the battery power, computation capacity, communication range and memory. They also are supplied with transceivers to gather information from its environment and pass it on up to a certain base station, where the measured parameters can be stored and available for the end user. In most cases, the sensors forming

SAMPLING IN WIRELESS SENSOR NETWORKS FOR ENERGY CONSERVATION Importance and Relevance and Novelty of the Project: 1. About Wireless Sensor Networks Now-a-days, deployment of wireless sensor networks for real-time applications has increased a lot. As and when, we talk about monitoring, transmitting (wireless), and controlling various physical conditions at a site, which we basically call a smart system, can be easily achieved by the wireless sensor networks. A wireless sensor network (WSN) comprises

Wireless Sensor Networks (WSNs) present universally and growing rapidly due to its unique features, such as their less weight, cheap, and wireless nature. However, due to its highly constrained computational and energy resources this network is exposed to numerous attacks that affect its security. So, it is important to address these security issues from the beginning of the system design. but, due to inherent resource and computing constraints, security in sensor networks poses diverse challenges
