In this paper, we consider energy harvesting cognitive radio networks (CRNs) where each secondary user (SU) has no fixed power supplies and extract energy only via harvesting energy by Radio Frequency (RF) provided by the control center (CC). Cooperative spectrum sensing is employed to improve the sensing performance. The spectrum sensing policy should maximize the probability of discovering and utilizing...
Rate adaptation, which adapts transmission bit rate according to current wireless link conditions, is a fundamental mechanism used by link-layer protocols to improve the performance of 802.11 wireless access networks in terms of throughput. However, rate adaptation faces to severe challenges due to more and more congested and dynamic wireless links. In this paper, we design a hybrid rate adaptation...
An extended seal calculus language, ExtSealL, and its syntax is introduced in this paper. A frame structure is proposed for ExtSeal. A construction method for translating a seal definition into the frame definition is proposed and a transformation function is given based on the method. An operating semantics is developed basing on the frame structure, an example of a frame and its execution are given.
