A NODE AND A METHOD PERFORMED BY THE NODE OPERABLE IN A MESH COMMUNICATION NETWORK FOR ROUTING A RECEIVED PACKET TOWARDS A DESTINATION
FIG1e is a flowchart of a method performed by a node operable in a mesh communication network for routing a received packet towards a destination, according to yet a further exemplifying embodiment
The method may further comprise, as illustrated in FIG1e, receiving 170 a warning packet associated with a node in the mesh communication network for which there is an entry associated with the sender of the warning packet in the routing table, and deleting 175 the entry from the routing table.

['1. A method (100) performed by a node in a mesh communication network for routing a received packet towards a destination, the method comprising: - receiving (100) a packet addressed to a destination node in the mesh network, the packet comprising information related to address of source node, last hop address, address of destination node, and a hop counter, - determining (120) whether the destination address is comprised in a routing table of the node in the mesh communication network, and when the destination address is comprised in a routing table: - forwarding (130) the received packet according to the routing table, or when the destination address is not comprised in a routing table: - flooding (140) the received packet by broadcasting it in the mesh communication network,  characterized in that , the method further comprising: - updating (150) the routing table according to the received packet, wherein the updating (150) of the routing table according to the received packet comprises incrementing a counter indicative of the number of times packets have been received from the last hop address, having the same source address, when both the source address and the last hop address are comprised in the routing table.', '6. The method (100) according to any of claims 1-5, further comprising receiving (170) a warning packet associated with a node in the mesh communication network for which there is an entry associated with the sender of the warning packet in the routing table, and deleting (175) the entry from the routing table.']
