Collection of autonomous computers referred as Computer Networks consists of various devices that are
attached to it needs to be completely secured from inside or outside threats. Threat an unwanted assault must be
mitigated in all measures by applying various cryptographic algorithms or models. Similarly, an attack is also an
important issue to be considered in networks both in case of wired or wireless mode of network arrangements. In
general Replay Attacks includes most vulnerable attack in case of wireless networks particularly, Wireless Sensor
Networks. We first propose the categories of attacks in the section one followed by the hardware architecture that
explains the sensor network arrangement in section two. This research proposal suggests the modular arithmetic to
identify the intruder detection analysis to pinpoint the adversaries where the networks are spoofed by false IP injection
packets in order to compromise the networks. Till date necessary authentication scheme are applied in various modes to
identify the intruding effect but applications are subject to vulnerable because of wireless modes. Normally, hacking
gets easily applicable in wireless devices due to the shared nature of the wireless medium, also through modifying the
Media Access Control (MAC) address of the network. This issue can be solved by the new proposal of modular arithmetic
approach which exactly identifies the intruder and blacklist them in order to quarantine them like a viral scanner tool in
section three. Further sections depict the pre-implementation procedure to notate the findings in order followed by
analysis that narrates the pinpoint inference of the attacks detected and solved. Any sensor node that is compromised
can be arranged through this modular arithmetic fashion but still the deployment cannot be possible in the initial stage.
The existing architectural pattern of sensor node arrangement is random, but security arrangements can be dynamic
and it is up to the organization to decide in infrastructural needs. The cost of node arrangement can also be considered
in the feasibility stage. The research proposal and the model can be applicable to any Advanced Encryption Standard
[AES] algorithms in the near future.
