Rancang bangun node dan protokol komunikasi untuk pengiriman informasi pada sistem monitoring batas wilayah darat menggunakan jaringan sensor nirkabel

摘要

Vulnerable to violations of the border issue so it needs to get serious attention. Wide area causing a border to be difficult to be monitored. Currently the use of peg-peg-monument boundaries with a small monument without a device to monitor the condition of the peg is still in use, so the theft / shift peg with the aim of extending territory by the other party is still happening. This final project is expected to help indicate early peg when there are uprooted. Nodes that diidentikan with the peg prepared on the historical line topology in a network. Preparation of the peg on the line topology is intended to make internode / peg in an inter-connected and if there are problems on one node / peg in particular can be detected by the node / peg in the other. FSK modem device that consists of modulator and demodulator XR-2206 XR- 2211 is used for coding digital data from the microcontroller into the form of frequencies to be transmitted via FM radio waves of 50 MHz. The test results showed that the device can communicate based on the concept of topological line with 96% success rate Keyword : modem FSK, transreceiver 50 Mhz.
