Performance Evaluation of IEEE 802.15.4 Ad Hoc Wireless Sensor Networks: Simulation Approach

Análisis del desempeño de una red Ad-Hoc inalámbrica móvil MANET, empleando el software NS 2.32 bajo el estándar IEEE 802.15

“…La PHY de 868/915 MHz, la de 868 MHz disponible para Europa, con una tasa de transmisión de 20 kbps soporta un solo canal y la de 915 MHz para EEUU soporta 10 canales, tiene una tasa de transmisión de 40 kbps, ofrece una solución a la congestión y las interferencias utiliza BPSK y CSMA-CA para múltiple acceso [7]. El estándar IEEE 802.15.4 fue creado en diciembre del 2004, este se encarga de definir un protocolo de interconexión para dispositivos de comunicación de datos con baja tasa de datos, baja potencia y baja complejidad.…”

Derivation of the Factors Influencing the Network Performance of Serverless Smart Exit Sign Systems Based on Wireless Sensor Networks

“…Kim et al [20] found that increased data traffic and radio signal communication cause packet collision, which degrades network performance. Wilson et al [35] argued that network expansion by multi-hop communication increases the packet error rate due to the increased number of packet collisions. Similar to maintenance work, security systems using sensor networks connect multiple nodes to a gateway node.…”

“…Several researchers have investigated the influence of 1 to n connections [7,17,20,35]. When many motes transmit packets to a single mote, packet collision and channel interference occur.…”

“…The packet error rate is decreased when expanding connected motes. [7,17,19,20,25,29,35] 1 to n connection test…”

Impact on Power Consumption of Zigbee based Home Automation Network using Various Traffic

“…One of the goals of Zigbee is to control and monitor environment using aggressive low energy transmission techniques so as to allow continuous use without changing battery for six months to two years [4,5].…”
