This paper presents a versatile heterogeneous sensor network simulator library that incorporates an online power model for real-time resource management research projects. The library integrates a well-known multi-agent simulator library Swarm, a popular sensor operating system, TinyOS, and a sensor network simulator tool called TOSSIM. The motivation of designing our library is to address difficulties...
During a crisis situation, the incident commanders have to tackle several problems simultaneously, e.g., (1) the monitoring of a crisis evolution, (2) guiding and tracking of rescue persons and intervention robots, (3) monitoring rescue persons' health, etc. Thus, several solutions based on wireless sensor networks (WSNs) and cellular networks have been proposed. However, the real life experience...
In this paper, a novel interoperable wireless sensor network (WSN) model using multi-agent-based middleware are proposed. This model provided generalized frameworks to address some critical issues existed in the WSN such as interoperability, time synchronization, power management and distributed computation. To address these issues, we developed a model that was based IEEE 1451 and IEEE 1588 standards...
Task allocation has been widely studied in high-performance computing environment. However, existing task allocation algorithms can not be directly applied to WSN because of the limited energy resources and computing capabilities of the Wireless Sensor Network (WSN). In this paper, we propose a new auction-based task allocation model for WSN and create an energy consumption based utility function...
Cooperative communications have been demonstrated to be effective in combating the multiple fading effects in wireless networks, and improving the network performance in terms of adaptivity, reliability, data throughput and network life time. In this paper, we investigate the use of cooperative communications for quality of service (QoS) provisioning in resource-constrained wireless sensor networks,...
Wireless sensor networks are increasingly seen as a solution to the problem of performing continuous wide-area monitoring in many environmental, security, and military scenarios.
A new method for target tracking based on multiagent and game theory is proposed in this paper. When a target occur in the sensing field of wireless sensor network, the sensor nodes begin to forming coalition dynamically and then they start to negotiate with game theory. New coalition is formed to track it with the target moving. Utilizing multiagent method and game theory in wireless sensor network...
A Wireless Sensor Network (WSN) is one that is in continual interaction with its environment, and executes at a pace determined by that environment. The use of rigorous formal method in specification and validation can help designers to limit the introduction of potentially faulty components during the construction of the system. Due to their complex nature, WSN are extremely difficult to specify...
In the last few years, WSN has been object of an intense research activity that has determined an important improvement by technologic and computation point of view both. The notable level got and the increasing request of applications designed over Sensor Networks make WSN commercial diffusion next to be a fact. One of key issues for commercial diffusion of WSN is related to the robustness of architectures...
Wireless Sensor Networks (WSNs) have an excellent application to monitor environments such as military surveillance and forest fire. However, in many scenarios, WSNs are of interested to adversaries and these sensor nodes are deployed in open and unprotected environments, the security of WSNs is still an important issue. Traditionally cryptographic mechanisms such as authentication and encryption...
This paper studies the routing problem in wireless sensor networks. Since the energy of a wireless sensor node is limited and recharging is difficult, while designing the routing protocol, saving energy is a primary concern. This paper proposes a routing scheme, denoted as intelligent agent routing for wireless sensor networks, which adopts the basic structure of agent routing mainly, to set up an...
