“…Mobility based algorithms: Some research works consider users with different mobility speeds and apply different CAC and vertical handoff algorithms for them. Some authors probabilistically reject vertical handoff requests to WLAN for highly mobile cellular users (Lampropoulos et al, 2005;Klein & Han, 2004), to reduce unnecessary handoffs. In this scheme, the processing load and new call blocking probability can be reduced while maintaining reasonable throughput in the WLAN.…”

“…However, the more are the desired signal components, the less the interference plus noise components are in a wireless system usually. Up to this moment, since the macrocell has a much larger communication radius than that of a femtocell, and the centralized deployment of microcell site is adopted generally, the methods of loading balance user were proposed in [3], in which the authors derived by using load balancing metrics to optimize the hierarchical wireless data networks. The research published in [4] has analyzed an operation planned underlay of a macrocell with single/multiple microcells.…”

In this paper the system performance of an MC-CDMA (multi-carrier coded-division multiple-access) system operating over single-cell with two-tier femtocell environment is analyzed. Consider two-tier scenario is deployed with a macrocell site in which is being surrounded several femtocells, which are designed to serve a group of subscribers locate in a small coverage area such as small office, home office or a house. The coverage area is typically up to 100 meters in radius. Mostly, the femtocell is applied to serve indoor subscribers, thus, the Rayleigh fading is adopted to characterize the propagation channel. The technique of TH-MC-CDMA (time-hopped multi-carrier coded-division multiple-access) technique is supposed to transmit each symbol alternatively with fair time (slotting)/frequency (coding) for each user in the hotspots (the area around 0 th femtocell). The intensity of signals estimated at a mobile unit located in the second tie, i.e., the femtocell coverage area, is an important issue. The contribution of the paper is mainly to evaluate the system performance with both the BER (bit error rate) and OP (outage probability) according to the most important parameters, for example, the activating user number, the hopping number provided by TH-MC-CDMA system and the subcarrier number. Furthermore, the discussion of interference avoidance is also discussed with non-analytically.

“…Avoiding packet losses using buffering and simultaneous binging to adjacent routers are also proposed and analyzed in (Salamah et al, 2003). In addition, some researchers are interested in assignment strategies for choosing between various communication layer and network architectures (Klein and Han, 2004).…”

Problem statement: Mobile Internet Protocol (MIP) is the forms of the backbone for next generation wireless internet technology to provide uninterrupted network service while a node on the move. The original MIP use Home Agent to forward the traffic. Thus, it does not have problem with simultaneous mobility, i.e., the special case when both end nodes are mobile and move at about the same time. However, MIPv6 uses location binding updates which sent directly to a correspondent node to complete its registration. Thus, MIPv6 is vulnerable to the simultaneous mobility problem which leads to the interruption of communication and cause messages lost, especially protocol messages. Approach: This article analyzed the simultaneous and successive fast mobility problems and handover latency. Then propose a mechanism by adopting technique to the mobile node's Home Agent. Results: We simulated the proposed scheme using ns-2 and we present and analyze the performance testing for the proposed scheme by comparing it with the conventional MIPv6. Conclusion: Simulation results showed this scheme can effectively resolve simultaneous and successive mobility problems and reduce the handover latency which is affected by long registration time.
