In this paper, we describe the cognitive radios sharing the spectrum with licensed users and its effects on operational coexistence with unlicensed users. Due to the unlicensed spectrum band growing needs and usage by many IEEE 802.11 protocols, normal wireless radio operation sees high interference leading to high error rates on operational environments. We study the licensed bands and the characteristics...
The paper is devoted to logical implication of MANet's protocols for gateway discovery in IPv6 Wireless Sensor Networks (IPv6-WSN). We implement three approaches in NS-2 simulator and evaluate its performance under the specified field of the networks of gateway discovery. The performance results present the packet delivery ratio and delay of end to end communication networks. The AODV protocol is...
The link layer routing protocols 6lowpan ad hoc on-demand distance vector routing (LOAD) and dynamic MANET on-demand for 6lowpan (DYMO-low) are integrated in 6lowpan stack. The stack is less complicated and it support IPv6 enabled packets route for biomedical data. Both routing protocols are modified and developed new approach for patient healthcare monitoring system. Thus, proposed integration method...
In this paper we analyze how radio frequency identification (RFID) technology can be used to efficiently and cost effectively achieve and improve the tracing and tracking in a monitored area network. In particular we describe implementational issues associated to tracing or tracking of any mobile platform (person, robot etc) equipped with a RFID transmitter. We present a `t-monitored area network'...
