Efficient and Robust Geocasting Protocols for Sensor Networks
Geocasting is the delivery of packets to nodes within a certain geographic area. For many applications in wireless ad hoc and sensor networks, geocasting is an important and frequent communication service. The challenging problem in geocasting is distributing the packets to all the nodes within the geocast region with high probability but with low overhead. According to our study we notice a cl...
متن کاملGeocasting in ad hoc and sensor networks
In a geocasting problem in ad hoc networks, a message is sent from one node to all the nodes located in a designated region. For example, monitoring center needs to contact all active sensors within a monitored area to either gather data from them periodically, or to provide its location to sensors covering certain area for event reporting. Intelligent flooding methods exist for this task when ...
متن کاملEfficient Routing Scheme for Opportunistic Networks
In the last few years research activity in Opportunistic Networks (OppNets) is growing and researchers have proposed various types of routing protocols. Context information is the main building block for design of these types of networks. This information is not always available which makes the design of efficient routing protocols is difficult. When context information is not available context...
متن کاملIdentifying Influential Nodes for Efficient Routing in Opportunistic Networks
—Opportunistic networks exploit human mobility and consequent device-to-device contacts to opportunistically create data paths over time. Identifying influential nodes as relay is a crucial problem for efficient routing in opportunistic networks. The degree centrality method is very simple but of little relevance. Although closeness centrality and betweenness centrality can effectively identif...
متن کاملFENC: Fast and Efficient Opportunistic Network Coding in wireless networks
Network coding is a newly developed technology that can cause considerable improvements in network throughput. COPE is the first network coding approach for wireless mesh networks and it is based on opportunistic Wireless Network Coding (WNC). It significantly improves throughput of multi-hop wireless networks utilizing network coding and broadcast features of wireless medium. In this paper we ...
