The collection tree protocol (CTP) is widely used in static wireless sensor network applications. With the increasing deployment of mobile WSNs, the performance of this scheme in mobile scenarios becomes extremely important. The motivation in using collection tree protocols over clustering and mobile ad hoc routing protocols is there simplicity resulting in reduced control packets but higher packet losses. We introduce the fixed node assisted-CTP (FNA-CTP) algorithm which aims to enhance the performance of CTP in mobile scenarios by tuning the parameters of CTP for the mobile and fixed nodes in order to reduce the messaging overhead required to maintain the network in mobile scenarios. We provide a detailed evaluation of the performance of FNA-CTP in different mobile sensor network scenarios through a set of simulations which indicates the superior performance of FNA-CTP and discuss various design issues associated with this scheme.
