Abstract—Wireless sensor networks (WSN) is a key innovation for the wireless network technology. It generally has a large number of sensor nodes with a power unit, a sensing unit, a processing unit, a storage unit, and a wireless transmitter & receiver. They are more vulnerable to attack then wired ones due to its nature and resources limitations. So as to overcome this security problems we can different types of Key Distribution and Hierarchical WSN. This paper gives more solutions to all problems

Abstract: Security is always a main task to be performed in any network. Wireless Sensor Network are different from other networks.Hierarchical Routing Protocol are the best energy saving and efficient rout wireless sensor networks. Our Objective is to Provide End to End Confidentiality in LEACH and Performance measurement of leach protocol for various homomorphic encryptions. Leach is a very secure Protocol as cluster head changes in each round but sometimes data needs to be very confidential of

tracking moving targets in a wireless sensor network (WSN). Until now, several methods have been presented for target tracking. These approaches face limitations that affect the efficient operation of WSN such as high energy consumption, high implementation cost and low speed or accuracy (e.g. Extended Kalman Filter and combination of Maximum Likelihood Estimation and Kalman Filter (KF+MLE)). Hence, other literatures have proposed methods which consider the sensor scheduling problem as finding the optimal

Introduction Wireless sensor networks have become an increasingly viable and effective form of aggregating information in recent years. They are being used in a variety of different industries, most notably including healthcare, environmental monitoring, and industrial applications. This survey paper will focus on the application of wireless sensor networks in healthcare. Wireless sensor networks present unique challenges to security that cannot be completely solved by using WLAN security mechanisms

Protection Problem Algorithms for Static Wireless Sensor Networks Nikitha Gullapalli Graduate Student, Dept. of Computer Science and Engineering, University of South Florida nikitha@mail.usf.edu Abstract — Wireless sensor networks are being widely used in many surveillance applications. Since sensor nodes are a critical part of sensor networks, certain level of protection needs to be provided to them. The self-protection problem focuses on using sensor nodes to provide protection to themselves instead

Service Discovery in Wireless Sensor Networks In [40],introduced simple service discovery protocol targeting to minimize the number of messages in the network while at the same time ,keeping the waiting time for services at minimal. Moreover,the performance of the stationary wireless sensor network is assessed. Remote procedure calls are used to retrieval a service once it is discovered, which permits for richer and parameterized interaction with the sensor. Enhancing peer-to-peer content

Sensor Network Lifetime Authors in [58], introduced an algorithm that exploit the sensor redundancy in the same zone by dividing the network into clusters thus the maintaining of the backbone connectivity can be done by retaining an important set of working nodes and close the redundant ones. Regarding the communication RTCP denotes equivalent nodes based on the connectivity information of one-hop neighbors which causes in reducing the communication overhead and then the scheduling of the nodes
