Wireless communication has taken big strides every decade as the next generation systems evolved. However, the wireless environment is plagued by several constraints; in particular, resource constraints. The electromagnetic spectrum being limited, the biggest hurdle in the development of advanced wireless systems is the lack of sufficient bandwidth. In the future, the number of simultaneous users and the volume of data communicated is expected to exceed by far the capacity of present day Cellular networks. With the advent of the Internet and wireless connectivity, there has also been an enormous increase in the number of applications that need special support from the network such as QoS guarantees. The research community has long since realized the dire need for networks with higher capacity and this realization has triggered vigorous research in the throughput enhancement of Cellular networks. This paper is a thorough performance study of two such novel throughput enhancement architectures viz. Integrated Cellular and Ad hoc Relaying System (iCAR) and Multi-hop Cellular Network (MCN). iCAR increases the network throughput by relaying excess traffic from a hot cell to cooler cells through a multi-hop path over special routers called Ad hoc Relaying Stations. MCN increases the network throughput by reducing the data transmission power to half of the cell radius, thus increasing the spatial reuse of bandwidth. A common property of these two architectures is the presence of hybrid characters i.e., the two architectures have attempted to benefit by combining the best of Cellular and Ad hoc systems. We identify the pros and cons of each and suggest enhancements based on our simulation results. Through this effort, we bring to light the general issues associated with throughput enhancement and prove the efficacy of introducing Ad hoc characteristics into traditional Cellular networks.
