Vehicular ad hoc networks (VANETs) have become a promising application of mobile ad-hoc networks (MANETs). Since an inaccurate traffic warning message will impact drivers' decisions, and misguide drivers' behavior, one of the main challenges in VANETs is to forward messages in such a way that the information content can be trusted by receiving nodes. In this paper, we proposed a reputation management...
Although some reputation schemes have been proposed for ad hoc networks, they are still not the most suitable for WMNs due to the special infrastructure and communication mode in WMNs. In this paper, a hierarchical reputation management framework for WMNs is presented. We show how to collect and query reputation values in an accurate, secure and efficient manner. The correlation validation algorithm...
The WWAN/WLAN two-hop-relay system integrates two types of wireless technologies to improve wireless access throughput and coverage. However, it is unreasonable to assume that all nodes are selfless and willing to relay for other users without an incentive. In this paper, a reputation management framework for Hybrid Wireless Relay Networks is presented. Based on this framework, we show how to collect...
In this project our goal is to create a health monitoring system that can transmit the vital signs of a patient through an ad-hoc wireless sensor network for a mass causality emergency application. The health monitoring device is to be placed on an injured victim during an emergency and act as a sensor node to connect to a wireless ad-hoc network to transmit the patient's vital sign data. The target...
Selecting an appropriate peer from the discovered file holders is one of the key steps in wireless peer-to-peer (P2P) file sharing systems. Most of existing peer selection schemes are based on the min-hops selection criterion, which uses the number of hops as the only factor in peer selection. However, due to the distinct characteristics in wireless mobile networks, a number of important factors should...
In an 802.11 wireless network with multiple access points (APs), for a commercial user, a prime concern is how to discover the desired AP since the AP providers maybe selfish and owned by different organization. This paper presents a generic reputation based framework for AP selection for this case. An M/M/1 queuing model is introduced to get a quantitative insight into the performance of wireless...
In most applications of wireless sensor network, the acquired information is useful only when their locations are known. Compared with ACT (alternating combination trilateration), IACT (improved alternating combination trilateration) has reduced its calculation overhead greatly. In IACT, The value of m, which determines how many triangles are used in calculations, is static. In this paper, the value...
