Quality of Service Analysis in Wireless Sensor Netw orks for Peer to Peer Topology
Sunil Patel, Surendra Kumar Kurmi · 2013
IEEE 802.15.4 is the emerging next generation stan dard designed for low-rate wireless personal area networks (LR-WPAN). The popularity of Wireless Sensor Networks (WSN) have increased tremendously in recent time due to growth in Micro-Electro-Mechanical Systems (MEMS) technology. WSN has the potentiality to connect the physical world with the virtual world by formin g a network of sensor nodes. The work reported in t his paper provides performance evaluation of quality of servi ce parameters for WSN based on IEEE 802.15.4 peer to peer topology. The performance studies have been evaluated for varying traffic loads using MANET routing pr otocol in QualNet . The data packet delivery ratio, average e nd-to-end delay, total energy consumption, network lifetime and percentage of time in sleep mode have been used as performance metrics. Simulation results show that D SR (Dynamic Source Routing) performs better than DYMO (Dynamic MANET On-demand) and AODV (Ad‐hoc On demand Distance Vector) routing protocol for varyin g traffic loads rates.
