Abstract :
Access to Wireless Sensor Networks (WSNs) from external applications will become a key aspect in order to successfully deploy this technology. This paper presents the Light-Weight Exterior Sensornet Protocol (LWESP), to enable the communication between applications and WSNs. This protocol is a combination of the Sensor Communication Language (SENCOMLNG) and the eXtensible Binary Enconding (XBE32). SENCOMLNG is an XML-based language. XBE32 provides an efficient encoding of the SENCOMLNG in order to reduce the bandwidth utilization and the processing cost in the WSN gateways, that in many scenarios could also be resource-restricted devices. Finally, we present a test-bed based on JAVA as well as a comparison between our proposal and other solutions showing that LWESP outperforms all the previous proposals in terms of bandwidth utilization.
