The IP Multimedia Subsystem (IMS) aims to provide cellular access to all the services that the Internet offers; it is an overlay control layer on top of an IP layer. Wireless Sensor Networks (WSN) with mobile sinks are useful in a wide range of scenarios since they can improve the overall network lifetime and increase data capacity. Combining the capabilities of IMS with the rich set of contextual...
The Host Identity Protocol (HIP) is an inter-networking architecture and an associated set of protocols, developed at the IETF since 1999 and reaching their first stable version in 2007. HIP enhances the original Internet architecture by adding a name space used between the IP layer and the transport protocols. This new name space consists of cryptographic identifiers, thereby implementing the so-called...
In this paper, we modify OLSR for MANET nodes to achieve full connection to Internet through multiple mobile gateways. We present a proactive mobile IP approach using Hello message and TC message to maintain the MANET nodes movement. The mobile gateway multiple metrics selection algorithm can select the best one among the active multiple mobile gateways. The simulation result shows that our approach...
A Wireless Mesh Network (WMN) is connected by multiple wireless mesh routers that are able to operate multiple channels for increased network capacity. As other wireless networks, the network capacity is a fundamental issue in the WMN. The analytical results in this paper show that the upper bound of network capacity lambda scales Theta(Wf/cradicn) if the number of infrastructure nodes m is significantly...
In wireless communication, Mobile Ad Hoc NETwork (MANET) is a set of mobile nodes that are dynamically and randomly located in such a manner that the wireless link among nodes are often changing due to MANET dynamic features. In this MANET environment, if a device wants to connect to Internet, it must establish a communication with an Internet Gateway. The network performance between mobile nodes...
In this paper, we modify AODV for MANET nodes to achieve full connection to Internet through multiple mobile gateways. We present a conditional hybrid mobile IP approach to maintain the MANET nodes movement. The mobile gateway selection algorithm can balance the Internet payload among the active multiple mobile gateways. The simulation result shows that our approach achieves excellent connectivity...
