Target Coverage and network connectivity are two main challenging and practically important issues of Mobile Sensor Networks (MSNs). Target coverage covers a set of specified points of interest in the deployment region of a WSN. Target coverage guarantees that every location in the sensing field is covered by at least one sensor and Network Connectivity guarantees that there are sufficient routing...
Over the past few years, wireless sensor networks (WSN) have emerged as one of the most exciting fields in Computer Science research. A Wireless Sensor Network (WSN) is a set of sensors that are integrated with a physical environment. These sensors are small in size, and capable of sensing physical phenomenon and processing them. The main aim of deploying applications based on WSNs is to make use...
Application domains such as scientific networks, blogs, and groups share information in a huge amount; this information is usually unstructured data in text documents. Document annotation is one of the popular methods, where metadata present in document is used to search documents from a large text documents database. Attribute-value pair annotations use either content or querying value of attributes...
The jamming attack is one of the major security issues where a jammer node interferes with the signal of neighboring sensor nodes and thus disrupts the message delivery of its neighboring nodes. In wireless sensor network which is having a broadcast nature as well as limited resources such as battery power, memory, computational capabilities these jammers can create mass destruction to legitimate...
The trend of location surveillance system is increasing day-by-day, so the range of such services providing systems like GPS and PDA's conjointly increase parallel. As a result of this, we tend to get the precise and applicable location of monitoring object. However at an equivalent time the foremost necessary issue of privacy is missing. WSN chiefly consists of spatially distributed autonomous sensors...
A MANET comprises of nodes with wireless radio interface is multi-hop network environment in which packets are transmitted from one to another node via intermediate nodes within range. To find an effective and an efficient routing protocol, which is used to transmit information from source to destination across whole network topology, is a major issue in networking research. Flexible and distributed...
