Abstract: Now a days, modernization of power grid plays a major role in reliable supply of electricity to meet the demand. The operating environment of power system is continuously monitored by sensors deployed in the transmission and distribution corridor. Information is periodically gathered through the sensors and transmitted to the control centre by relay node or master node of the transmission tower. Based on received information, control centre will take faster and smarter decisions. Traditional wired communications cannot meet the communication needs of online monitoring of transmission lines due to its complex nature. A combination of multiple wireless technologies (GPS, RFID, WLAN and cellular) with contemporary data analysis techniques is applied to reduce the complexity of data retrieval from transmission system. However, during the transmission of data, low data rate wireless devices cause bandwidth and latency bottleneck in Wireless Sensor Networks (WSNs). This problem can be reduced to certain level by optimally placing the direct cellular links in selected transmission towers. This study describes a novel shortest link path algorithm for optimal placement of direct cellular link respecting the delay and bandwidth constraints.
