Scope and Objectives

SIGGCN focuses on cellular networks, defined as networks that deliver broadband services to mobile users over a large geographical area, as exemplified by 3G systems today. The current architecture of 3G networks is homogeneous, with base stations communicating directly or through repeaters with mobile users. In the future, cellular networks are likely to adopt a heterogeneous structure, with two or more tiers of access points having widely differing coverage areas and capabilities. This SIG would therefore cover both the homogeneous structure of the present and the heterogeneous structure of the future. A combination of cooperation and cognition in order to reduce energy usage is an example of a research thrust that will be supported. The integration of energy harvesting into a large-scale communication network is another example.

Aside from network architecture, resource allocation and other cross-layer optimization problems related to cellular networks will be covered. For instance, with uncertainty in the amount of power generated from renewable energy sources, reliability in terms of outage can be traded off against delay, which leads to a fundamental change in scheduling strategies. Similarly, if energy efficiency is the main goal, opportunistic scheduling of users with delay-tolerant traffic having the best channels may be desirable. These and related problems will fall under the scope of this SIG.

Finally, at the physical layer, the power consumption of transceivers in mobile and infrastructure devices will be a key parameter that requires more intricate and accurate modeling, and must be accounted for in any green system design. If a receiver structure that performs better in terms of bit error probability consumes more power, it may not be an attractive option. If a coding scheme performs closer to the fundamental limit but at the cost of greatly increased encoding complexity, again it may not be the best choice. In other words, it is critical to develop a more sophisticated, unified way of evaluating performance at the physical layer that emphasizes energy efficiency, compared to traditional approaches that rely on outage and error probabilities alone. The PHY layer will therefore also be a key component of this SIG.

In summary, this SIG will concentrate on energy efficiency and integration of renewable energy sources into cellular networks, defined as those that deliver broadband communication services to mobile users over a large geographical area. The sub-areas of interest can be divided into:

  • Network architecture e.g. heterogeneous or multi-tier structure and how that can help to reduce energy usage and reliance on carbon-based energy;
  • Cross-layer optimization e.g. resource allocation based on trading off one measure of performance against another;
  • Physical layer design e.g. accounting for power consumption when evaluating the performance of coding, modulation and receiver schemes.
