Method for routing a message at a wireless node in a wireless network

A method for routing a message at a wireless node in a wireless network having a grid topology, the wireless node having a source identification number SID and located at a column SC and a row SR of the wireless network, the method comprising:

• receiving, by a wireless transceiver, a message including a first next hop address and a destination node identification number, DID carried in a first wireless signal, the message carrying data generated from a sensor in the wireless network;
• wherein the wireless transceiver comprises the processing circuitry and a memory, an input/output interface, a signal bus and an antenna, wherein the wireless transceiver, the input/output interface and the antenna are coupled together through the signal bus;
• determining, by a processing circuitry, whether the source identification number SID is the same as the first next hop address;
• and
• when the source identification number SID is the same as the first next hop address,
• calculating, by the processing circuitry, a destination column DC and a destination row DR based on the destination node identification number DID;
• determining, by the processing circuitry, a second next hop address of a next hop by comparing the destination column DC, the destination row DR, and the destination node identification number DID with the column of the wireless node SC, the row of the wireless node SR, and the source identification number of the wireless node SID without discovery of routes to other nodes in the wireless network and routing table maintenance, wherein the next hop node is one of neighboring nodes of the wireless node, and
• transmitting, by the wireless transceiver, the message including the second next hop address to the next hop node on a second wireless signal,
• wherein the wireless network includes a plurality of wireless nodes that are arranged in columns and rows, and are sequentially assigned, row by row and column by column, with a sequence of identification numbers.
