Practical Cellular Performance Bounds via Shotgun Cellular Systems
This paper considers two-dimensional interference-limited cellular radio systems. It introduces the shotgun cellular system that places base stations randomly and assigns channels randomly. Such systems are shown to provide lower bounds to cellular performance that are easy to compute, independent of shadow fading, and apply to a number of design scenarios. Traditional hexagonal systems provide...
متن کاملSecure Communication in Shotgun Cellular Systems
In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملDynamic Channel Assignment in Shotgun Cellular Systems
This paper analyzes dynamic channel assignment in cellular systems where the base stations are placed at random. Using a simple dynamic channel assignment algorithm, random systems are compared to an ideal hexagonal systems. Under log-normal shadow fading the random system has capacity within 1dB of the hexagonal system. This paper looks at both the uplink and downlink and finds that performanc...
متن کاملBounds and Performance of Reuse Partitioning in Cellular Networks
In this paper we study a scheme that allows a smooth increase of the capacity of a cellular system for circuit switching by applying cell partitioning and using dynamic channel allocation techniques. A bound is computed for this reuse partitioning scheme that gives the maximum theoretical gain accomplished in the system bandwidth. The performance of the proposed scheme in terms of blocking prob...
متن کاملPerformance Bounds for Mobile Cellular Networks with Handover Prediction
We determine the gain that can be achieved by incorporating movement prediction information in the session admission control process in mobile cellular networks. The gain is obtained by evaluating the performance of optimal policies achieved with and without the predictive information, while taking into account possible prediction errors. We evaluate the impact of predicting only incoming hando...
