Current research proposes the Scheduling Based Energy Efficient Mobile Node Communication in Wireless Sensor Networks Unmanned Aerial Vehicle. In this work, hybrid network consists of two types of nodes one is static nodes and other are moving nodes. We will consider these mobile nodes as mobile sink. Each static sensor has fixed or low energy. They have limited memory buffer. According the siz...

In this paper, we consider a sink location in a dynamic network which consists of a graph with capacities and transit times on its arcs. Given a dynamic network with initial supplies at vertices, the problem is to find a vertex v as a sink in the network such that we can send all the initial supplies to v as quickly as possible. We present an O(n log n) time algorithm for the sink location prob...

Localization of sensor nodes is important in many aspects in wireless sensor networks. The known location of sensor node helps in determining the event of interest. A mobile sink is introduced to track the event driven sensor nodes in the path of the event, thus conserving energy and time. We present a novel range based localization algorithm which helps the mobile sink to compute the location ...

The deliberation of interloper is to interrupt the communication or to invade the location of sender and receiver. One of the primary concerns of wireless sensor networks is the privacy of sender and receiver. There is always a threat of eavesdropper. The chief objective of this paper is to achieve a high degree of security for both source and sink. Due to an open characteristic of wireless sen...

A wireless sensor network (WSN) is composed of numerous small sensing devices with limited communication range. The sensors collect data from the environment and report them to the sinks. With the promising sensing and wireless technologies, sensor networks are expected to be widely deployed in a broad spectrum of civil and military applications. Location information of the sinks, the sensors, ...

Wireless Sensor Network (WSN) is a broad network consisting of a number of sensor nodes in it. WSN is used mainly for monitoring and data aggregation purpose. A best plan of opponent may attack the sink node which is the aggregation point for the whole network. So, first there comes a need to secure the sink node from adversary. There are previous work are done by providing location privacy to ...

A dynamic network N = (G, c, τ, S) where G = (V,E) is a graph, integers τ (e) and c(e) represent, for each edge e ∈ E, the time required to traverse edge e and its nonnegative capacity, and the set S ⊆ V is a set of sources. In the k-Sink Location problem, one is given as input a dynamic network N where every source u ∈ S is given a nonnegative supply value σ(u). The task is then to find a set ...

Sink mobility has been utilized in numerous schemes to prolong the lifetime of wireless sensor networks (WSNs). Among the many ways of improving the performance of a WSN in terms of crucial metrics such as its lifetime and data latency, utilizing the mobility of some of the network components has been recently observed to be among the most promising. Regardless of its numerous advantages, deliv...

The sink location problem is a combination of network flow and location problems: From a given set of nodes in a flow network a minimum cost subset W has to be selected such that given supplies can be transported to the nodes in W . In contrast to its counterpart, the source location problem which has already been studied in the literature, sinks have, in general, a limited capacity. Sink locat...
