Abstract:
Wireless communication and mobile computing have gained a
lot concentration from the computer and communication research
society. Wireless dissemination has emerged as an outstanding
and scalable method to broadcast information to huge number of
clients equipped with hand held devices. In practice, wireless
broadcast faces challenge from issues like timely delivery of
data, error free quality of service, low battery capacity and
limited bandwidth. Different applications need to curb out
different challenges. To support location based services in
wireless data broadcast system a distributed spatial index (DSI)
is popular. DSI indexing technique is in recent times has been
becoming popular as reduce access time and energy consumption
in location based queries because it has a linear yet fully
distributed structure that facilitates multiple search path to be
naturally mixed together by sharing links. Here, in this paper we
address an issue where error free timely delivery of information
is major concern. Such state of affairs generally appears in an inhouse
environment where recharging of battery is not a serious
concern. We have proposed a Data Replicated Distributed
Spatial Index (DR-DSI) which is extension of Distributed Spatial
Index to get advantages of data replication to reduce access
latency.
