The nature of the path constructed is very important in the routing process. If we are able to construct the path between sensor node and base station in a straight line or near to straight line, then the efficiency of data transfer will be very high. The nodes appear in the straight line can be found using the angle measurement technique using cosine of the angle between current node,probable next node and base station. If this angle is maximum among the probable next node candidates; then the maximum cosine angle will form path which is approaching to a straight line. The current work prepares the routing table based on this angle measurement approach, which is con- structed statically particular time duration. The path will be constructed statically using these RT entries. The data will later use this path to take the data towards base station. The simulation compares two different RT search criteria. In the first approach is entry in the RT is used. while in the 2nd approach, maximum angular entry is found out and used as the next forwarding node. In the path construction process which is static as far as current work is considered. The simulation result is compared against the normal next node selection, where the first entry in the routing table is selected in the path construction process.
