We propose a Rank-Based Data Gathering (RBDG) algorithm for wireless sensor networks with randomly distributed sensor nodes. For every round of dasta communication, the algorithm functions as follows: A set of sensor nodes or vertices are assigned a random rank between 0 and 1. A link is formed between any two nodes if they are within each other‘s transmission range. If a sensor node has the hi...
The main goal of wireless sensor networks (WSN) is to gather data from their environment. This gathering should take into consideration the life of the battery of each sensor node to maintain the continuity of the network. The technology of multi-agent system (MAS) can be adopted in large scale WSN for reliable wireless communication with high energy efficiency. In this paper, we propose a sche...
due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and 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 comprehensive omni directional mobile robot. such...
Wireless mobile sensor networks (WMSNs) are groups of mobile sensing agents with multimodal sensing capabilities that communicate over wireless networks. WMSNs have more flexibility in terms of deployment and exploration abilities over static sensor networks. Sensor networks have a wide range of applications in security and surveillance systems, environmental monitoring, data gathering for netw...
Energy conservation is a vital issue in wireless sensor networks. Recently, employing mobile sinks for data gathering become a pervasive trend to deal with this problem. The sink can follow stochastic or pre-defined paths; however the controlled mobility pattern nowadays is taken more into consideration. In this method, the sink moves across the network autonomously and changes its position bas...
Mobile nodes are used to solve the problems existing in static wireless sensor networks such as energy hole, overlapping and hot spot etc. Through data gathering and relaying, mobile nodes can reduce the amount of data transmitting between the static nodes, which can conserve the power of these nodes and therefore to prolong the lifetime of network. In this paper we describe the DataTruck, a ne...
We consider a Gathering problem for n autonomous mobile robots with persistent memory called light in an asynchronous scheduler (ASYNC). It is well known that impossible when have no lights basic common models, if the system semi-synchronous (SSYNC) or even centralized (only one robot active each time). can be solved by 10 colors of ASYNC. This result obtained combining following results. (1) T...
