“…In some dynamic location management schemes [1,3,12,15], extensive computations must be done at the mobile host. However, a good strategy of the location management should efficiently use the limited resource of PCS and not require expensive computation at the mobile host.…”

“…To solve the location management problem, various architectures of distributed databases have been proposed to store the locations of mobile users, like the famous two-tier architecture [16], the hierarchical architecture [16], and many other strategies of location management [1][2][3][9][10][11][12][13]15,17]. There are two purposes of developing these location management schemes.…”

How to reduce location updating traffic is a critical issue for tracking the current locations of users in a personal communication system. Traditional location management approaches usually bring about network overload or bottleneck of the HLR when a mobile user moves back and forth between adjacent location areas. So far, many works have focused on this research topic to solve the location updating rate or the location updating cost. In this paper, we shall employ both concepts of time stamp and virtual overlapping to propose a newly developed scheme for reducing both the location updating rate and the location updating cost. From the simulated results, our scheme can significantly reduce the location updating traffic.

Abstract. To reduce the transmitted power of base stations in mobile wireless networks, continuous cell zooming algorithm is a feasible dynamic cell zooming algorithm. In this algorithm, location management is required in order to know the locations of users. Movement-based Update is not compatible and the application of Convention Periodic Update (CPU) scheme in continuous cell zooming algorithm can lead to a high signaling cost. Thus, aiming to highlight the effectiveness of newly proposed location update schemes, Time-Adaptive Periodic Update (TAPU) and Location-Adaptive Periodic Update (LAPU), a simulation-based performance analysis is conducted. Applying in continuous cell zooming algorithm, the performances of TAPU and LAPU are compared to that of Convention Periodic Update (CPU) scheme in terms of transmitted power ratio, outage ratio and the number of update messages. The performances of TAPU and LAPU are analyzed in a network with different number of users and in a network with different average moving speeds of users. The results show that compared to CPU, both TAPU and LAPU have no significant effect on power saving capability of continuous cell zooming algorithm in every scenario. Meanwhile, LAPU and TAPU give a significant reduction of update messages in every scenario. In terms of QoS effect, LAPU gives approximately the same outage ratio as CPU and a higher outage ratio occurs in TAPU.

“…A survivable network has the ability to withstand malicious attacks and to continue to work properly even in the presence of natural or man-made disturbances. It focuses on delivery of essential services and rapid recovery of full services when situation improves [2], [3]. Mobile networks have the challenge of survivability, since the communication channels are accessible to anyone.…”

Mobile networks (NEMO) can be formed with IPenabled devices in motion. Mobile Router (MR) acts as the gateway for all the nodes inside a mobile network. As the MR is the key entity in NEMO, the load on MR can be very high and can become the performance bottleneck. Increase in number of MRs can improve the reliability, as a single MR can be single point of failure. There have no survivability analysis of NEMO based on multiple MRs. In this paper, we have performed quantitative survivability analysis of NEMO with multiple MRs, taking into consideration possible node and link failures along with denial of service attacks. We have presented numerical results which reveals that increase in number of mobile routers improves the performance of the mobile network by reducing the mean delay and drop probability while withstanding attack packets.
