1. A routing method of a sensor node using a time division access scheme, wherein the sensor node is associated with a plurality of neighboring nodes, the method comprising:
- transmitting a beacon to at least one of the neighboring nodes in a first time slot within a second beacon interval that is allocated to the sensor node;
if a beacon comprising routing information is not received from any of the neighboring nodes in a first beacon interval occurring before the second beacon interval, then receiving a beacon in the second beacon interval only from each of the neighboring nodes that is connected to the sensor node by a routing topology; and
if a beacon comprising routing information is received from at least one of the neighboring nodes in the first beacon interval, then receiving a beacon in the second beacon interval from each of the neighboring nodes.

Abstract
Provided are a sensor node of a low power for a monitoring application in a mesh sensor network using a time division access scheme, and a routing method thereof. The routing method of the sensor node may include: transmitting a beacon containing routing information to neighboring nodes in a first time slot within a first beacon interval that is allocated to the sensor node; and receiving a beacon from each of the neighboring nodes in a second time slot within a second beacon interval that is allocated to each of the neighboring nodes.

7. A sensor node using a time division access scheme, wherein the sensor node is associated with a plurality of neighboring nodes, the sensor node comprising:
-
a transmitter to transmit a beacon to at least one of the neighboring nodes in a first time slot within a second beacon interval that is allocated to the sensor node; and a receiver, wherein; if the receiver does not receive a beacon comprising routing information from any of the neighboring nodes in a first beacon interval occurring before the second beacon interval, then the receiver receives a beacon in the second beacon interval only from each of the neighboring nodes that is connected to the sensor node by a routing topology; and if the receiver does receive a beacon comprising routing information from at least one of the neighboring nodes in the first beacon interval, then the receiver receives a beacon in the second beacon interval from each of the neighboring nodes. - View Dependent Claims (8, 9, 10, 11, 12)
