Large crowds at music festivals or other mass events create challenging environments for traditional infrastructure based wireless networks. Mobile devices carried by the attendees produce large amounts of network traffic that can result in network outage or serious delays. Opportunistic networks may offer solutions to enable communication between attendees and/or organizers through direct communication...
In this paper, the requirements of survivability of MultiHop Wireless Network (MWNeT) was analyzed firstly, then we classify the impacts that affect survivability into three categories: dynamic topology, faults and attacks, and the impacts of these factors are analyzed individually. A simulation environment for the MWNeT towards survivability is designed and implemented as well. Experiments that under...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
