“…These results will be presented along with the simulation results obtained using the ns-2 discrete [13,24,25] in order to validate the mathematical model. The data packets are 10 backoffs slots length and a data rate of λ packets per packet duration will be set, therefore, the maximum data rate for a node is λ = 1, in this case the node generates a 10 backoffs slots packet every N = 10 backoffs.…”

The IEEE-802.15.4 standard is poised to become the global standard for low data rate, low energy consumption Wireless Sensor Networks. By assigning the same sets of contention access parameters for all data frames and nodes, the Contention Access Period (CAP) of the slotted IEEE-802.15.4 currently provides an even channel access functionality and no service differentiation. However, some applications may require service differentiation and traffic prioritization support to accommodate high-priority traffic (e.g., alarms). In order to simulate a scenario in which different sets of access parameters for different node classes can be configured, this paper develops a Markov-chainbased model of the CAP of the IEEE-802.15.4-MAC. Our Markov model can be used to evaluate the impact of mixing node classes in important factors like the throughput, energy consumption, probability of delivery and the packet latency. The model has been used to provide traffic differentiation in a high saturation scenario in which a set of nodes can be configured to increase 76% the probability of sending a packet and reduce 58% latency, with a 69% energy penalty, in comparison with a standard scenario. The accuracy of the Markov model is validated by extensive ns-2 simulations.

In today's era of technology, everything is integrated on smart phone. Every common man has a smartphone and carries it everywhere. When people travel to any new place, in order to locate and find path to their destination, they use GPS in their smart phones. But GPS is not precise for small scale and does not work inside the buildings; therefore the need of indoor positioning arises. Our motivation behind the project is to come up with indoor navigation application that can help any new visitor to locate and find path to their destination easily inside the campus. Indoor navigation application uses BLE beacon. BLE beacon allows mobile application to determine their location on a microlocal scale. Beacon and smartphone use Bluetooth Low Energy technology for communication. Since it uses Bluetooth Low Energy for communication it consume very less battery power.

“…The MAC control and Beacon frames uses a slotted CSMA/CA mechanism to access the channel. Data frame that follows the acknowledgment of a data request command but acknowledge frame doesn't follow the slotted CSMA/CA mechanism [7,8]. An IEEE 802.15.4 WSN is consist of a parent PAN coordinator and a set of children and parent nodes.…”

This research work is based on IEEE 802.15.4/ Zigbee wireless sensor network. The main aim of this research is to analyze the performance of Zigbee network topologies in beacon enable mode by giving the random waypoint mobility model to its nodes. The scenarios have investigated the performance of network by varying speed and mobility of nodes. Results are evaluated using parameters throughput, data traffic sent and data traffic received and number of hops. The simulation is done by OPNET modeler 14.5. The results conclude that tree topology give good performance in case of data traffic sent and data traffic received, the throughput is also efficient. Hence tree topology constructs a robust network using mobile nodes.
