  • Abstract A wireless ad hoc network is a special type of wireless network which has no
    infrastructure and does not need any well-planned deployment. This thesis discusses the
    Zone Routing Protocol (ZRP), proposed to find the route in wireless ad hoc networks.
    When the destination node is not within the zone of the source node, query messages are
    sent to find the path. To preserve the network resource, it is important to reduce the
    number of query messages sent. There are three query control schemes for ZRP: query
    detection, early termination, and random query processing delay. All these schemes are
    based on marking those nodes which should not retransmit the query messages. This
    thesis evaluate the effectiveness of the query control schemes in both fixed and mobile
    networks. The simulation results suggest that the following findings. In fixed
    network query control reduces the number of, either received or transmitted, query
    packets. In mobile networks query control does not affect the number of transmitted
    query packets but slightly increases the number of received query packets. When the
    nodes are allowed to move around freely, the zone membership of ZRP is hard to
    maintain. Hence the query control is not as effective as expected. It may be worth
    considering disabling the query control for saving the power consumed by computing the
    query control schemes.
