Fine-grained frequencies have been used for IEEE 802.15.4 based communication in several recent works to enhance network throughput as well combat Cross Technology Interference (CTI) licence free ISM bands. However, the demonstrate that Center Frequency Distance (CFD) goes very low (<3 MHz), adjacent channels start severely interfering with each other which heavily limits use of fine-grained fr...

While the Differentiated Services (DiffServ) infrastructure is scalable and robust in providing network Quality of Service (QoS), there are serious drawbacks with the services provided by DiffServ: (1) the services are coarse-grained and oneway only; (2) no service differentiation and resource isolation are provided to meta-data packets such as TCP SYN and ACK packets. Moreover, the coarse-grai...
