Omni directional mobile robots have been popularly employed in several applications especially in soccer player robots considered in Robocup competitions. However, Omni directional navigation system, Omni-vision system and solenoid kicking mechanism in such mobile robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, a comprehensi...

this paper presents an optimal integrated instrumentation sensor network design methodology for complex nonlinear chemical process plants using a combinatorial particle swarm optimiazation (cpso) engine. no comprehensive sensor network design approach has been addressed yet in the literature to simultaneously incorporate cost, precision and reliability requirements for nonlinear plants. the pre...

The paper investigates the problem of achieving globally optimal coverage for non-convex grid environments with a network of mobile sensor nodes. A distributed algorithm is proposed to solve the problem, which is locally implementable on individual sensor. That is, each mobile sensor only requires to update its current position to an adjacent location with certain probability relying on its cov...

Wireless Sensor Network Systems can be applied to monitor different environments ranging from military to civil applications. It has been observed that different protocols required for smooth functioning of the network system are highly application specific. Another important fact is that the communication protocols have significant role in achieving right performance of the network system. In ...

A sensor network is nothing but the collection of number of wireless mobile nodes. Each node route the packet as well as forward the packet until the destination. Many routing protocol have been developed in mobile networks. Protocol selection is the main purpose of the wireless network and selected protocol must be best in all aspects of the mobile network. In this paper, simulation performanc...

Distributed sensor networks (DSNs) are being developed for a wide range of applications. A sensor network consists of a large number of nodes performing distributed sensing/event detection. Sensor nodes are energy-constrained, efficient routing is essential for increasing the lifetime of a sensor network. A DSN requires interoperability, low latency, and low power consumption in order to operat...

Wireless sensors are used in many areas such as environmental and habitat monitoring, indoor climate control, medical diagnostics, intelligent alarms, surveillance and many more. Since sensor nodes are placed in remote areas and require less attention and supervision, a significant number of these nodes require battery power to survive long periods of time. Recharging or replacing the battery i...

The Sinks are vivacious in many wireless sensor network (WSN) solicitations for competent data accumulation, confined sensor reprogramming, and for extricating and revoking conceded sensors. However, in sensor networks that make use of the temporal key dissemination schemes for pairwise key naissance and endorsement between sensor nodes and mobile sinks, the engross of mobile sinks for data ass...

A Wireless Sensor Network (WSN), consisting of a huge number of small devices called sensor nodes (each with wireless communication functionality, various sensors, a processor, and a power source), is a network system that can communicate and use sensing data gathered mutually by each spatially distributed sensor node. An ad-hoc network connecting each sensor node one by one can be constructed ...

Recent research has shown that using a mobile element to collect and carry data mechanically from a sensor network has many advantages over static multihop routing. We have an implementation as well employing a single mobile element. But the network scalability and traffic may make a single mobile element insufficient. In this paper we investigate the use of multiple mobile elements. In particu...
