As an important parameter of network, Blocking probability has been investigated in various type of networks such as GSM, WLAN, etc. In this paper, blocking probability of mobile router in Mobile network (NEMO) is investigated with analytical model of Markov chain, considering two factors of node mobility model and call arrival rate. First we describe NEMO architecture, then three types of Mobile...
In this paper, we present a scheme for multicast access control. The proposed solution makes use of the Rendezvous Point(RP) of PIM-SM for collecting and updating keys to implement a distributed shared-key based multicast access control system. We name this PIM-SM based access control scheme PIMac. PIMac supports both receivers and senders access control, realizes host exclusion based on expire time...
In this paper, a novel mechanism of mobile seamless handoff based on MPLS multicast is proposed on the basis of analyzing handoff latency combining Hierarchical MIPv6 (HMIPv6) and Fast MIPv6 (FMIPv6). By searching the cross LSR with an effective and simple method, we rebuild the LSP from it to new access router and create dynamic buffer on the cross LSR. So we could minimize LSP path that need to...
The least mean square time delay estimate (LMSTDE) algorithm is independent of the prior knowledge of signals and noises. Under the LMS criterion, the best estimate is acquired by automatic adjusting related parameters. In this paper, we applied LMSTDE to estimate the propagation velocities of four-channel gastric myoelectrical recordings that were obtained from implanted gastric serosal electrodes...
