Tagciti is a novel location-aware and socially-relevant information creating and discovering service for mobile users. Instead of depending on commercially created location related information, Tagciti provides users the necessary means to become part of the information creation process. It enables the creation of dynamic, up to date, and socially-relevant shared information. Also, it provides an...
The IP tunneling mechanisms have important applications in network solutions and are widely used in numerous contexts such as security (VPN), IPv4 to IPv6 transition, and mobility support (MobileIP and NEMO). However, these tunneling mechanisms induce a large overhead resulting from adding several protocol headers in each packet. Moreover, this header overhead could be found on wireless links which...
Wireless mesh networks used for broadband access may be equipped with multiple Internet gateways. Using airtime metric as the main criterion for path selection is an effective method for achieving load-balancing in such a multi-homed mesh network. In this paper, we describe how the radio-aware path selection using airtime as a metric can be implemented in order to achieve this functionality, based...
Wireless sensor networks present a great potential in monitoring systems. A vast scope of applications can take advantage of WSNs and, mainly because of their own nature, the aggregation of WSN nodes into groups provides more potential solutions when compared with traditional monitoring systems. This paper introduces the issue of multicast messages and their impact on battery resources of WSNs. It...
Wireless mesh networks will play an important role in the next-generation wireless communication systems as it can provide wide coverage and scalable broadband Internet access services. However, congestion in such networks may lead to throughput degradation, packet loss and longer transmission delay. Therefore, routing and traffic forwarding schemes which are aware of the congestion status of a wireless...
