Cell Outage Compensation (COC) is a self-healing functionality in the overall Self-Organizing Networks vision, which is defined by 3GPP. The Operation Administration and Maintenance system triggers the COC for mitigating the outage problem, e.g. out-of-service cell, by providing an adequate level of service to the affected users in the outage cell. We propose an outage compensation algorithm based...
The base station (BS) deployment planning is become more complex for the next-generation wireless networks, which is an architecture with multi-tier topology. The multiple coexist networks are deployed to serve different kinds of mobile users that their traffic requirements and moving speeds are different. Thus, in this paper, we discuss how to deploy the heterogenous BSs that support different service...
Traffic evaluation is very important for wireless network planning. We should provide enough resources (channels) for conveying the traffic load. Next generation wireless networks are all based on IP. In this path, voice is also handled as VoIP. In this paper considering Eb/No, data rates, source activity factor and other cells interferences in a multi-user system, we first calculate the number of...
This paper introduces a novel architecture for mobile communication networks with guaranteed quality of service. For comparison purposes, performance upperbounds of the whole system are derived subsequently. Their numerical evaluation in real-life simulation scenarios shows that our proposal significantly outperforms the state-of-the-art IEEE 802.11 technology in random topologies with varying traffic...
A distributed scheduling approach for fast deployable tactical IEEE 802.16e networks is presented where distributed base stations with dual radios form a mesh backhaul and mobile battle units communicate through these base-stations. The mesh backhaul is formed via an IEEE 802.16e mesh mode radio on each base station, while mobile units communicate with base stations via PMP mode radios. The scheduling...
Our previous work proposed a novel mechanism for coverage control in WCDMA systems that can be used in instances of congestion and load imbalance. In this paper, we expand our work to accommodate the heterogeneous nature of traffic in future networks. More importantly, we derive a mathematical model to involve more realistic considerations for inter-cell interference in a system with mixed coverage...
Todaypsilas access network is migrating towards broadband IP, fixed/mobile convergence and service convergence. Thus, the next generation access network (NGAN) requires a converged optical/wireless access network infrastructure, other than the existing architecture that connect to the cellular, broadband wireless, and optical access networks separately, which complicate the network and increase the...
