grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

sybil attacks pose a serious threat for wireless sensor networks (wsn) security. they can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. in a sybil attack,the attacker masquerades as multiple sensor identities, that are actually controlled by one or a few existing attacker nodes. sybil identities are fabricated out of stolen keys, obt...

Routing protocol for wireless mobile sensor networks can be active, can also be passive. The network all wireless sensor node is base station and the gateway for two-way communication. To complete the training parameters, which can be called the training function is used to train the BP neural network. The paper presents design and implementation of wireless sensor network nodes based on BP neu...

wireless sensor networks(wsn) have unique properties that distinguished them from other wireless networks and have special challenges. not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. because of the importance of covers in wireless sensors, in this work ...

sink location is considered as a basic service in geographic routing in wireless sensor networks. obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. in this paper, a sink location algorithm based on fano plane is proposed. the research challenge is how to ensure the intersection of two slq and sla rou...

A mobile wireless sensor network owes its name to the presence of mobile sink or sensor nodes within the network. The advantages of mobile wireless sensor network over static wireless sensor network are better energy efficiency, improved coverage, enhanced target tracking and superior channel capacity. In this chapter we will present and discuss different classifications of mobile wireless sens...

The wireless sensor network is used to solve problems in real world such as industrial and environmental Sensing. There are two types of Wireless Sensor Network, Mobile and Static. They are the Wireless Sensor Network are prone to attacks. The most prominent attack in Wireless Sensor Network is node replication attack were the nodes are replicated virtually. The replicated node captures the key...

Wireless sensor network can be used in military application for monitoring militant activities like tracking enemies, force protection and monitoring the vital signs of the soldiers who are in a battlefield. Wireless sensor network has set of distributed sensor nodes which are connected to each other. These sensor nodes are low powered, low cost, small in size with limited amount of battery sup...
